TECHNICAL FIELD
[0001] The present application relates to the technical field of thermal fluid simulation, in particular to a thermal fluid composite material dynamic effect simulation method and system. BACKGROUND
[0002] In the field of human-computer interaction, entity interaction interfaces with variable color surfaces have been widely studied. The appearance of these variable color interfaces can usually be programmably designed and controlled, so as to be applied to information transmission or aesthetic expression by researchers and designers. In recent years, the research trend in this field focuses on, on the one hand, realizing dynamic display on surfaces of arbitrary shapes (such as curved surfaces or flexible surfaces), thereby expanding the functionality and expressiveness of the interface; on the other hand, embedding such dynamic display capability into various common materials (such as paper or fabric), thereby preserving the familiarity and aesthetic sense of the interface itself.
[0003] To this end, the academia has conducted a large amount of research on the implementation mechanism and technical means of variable color interfaces: most of the work produces variable color interfaces by drawing thermochromic pigments on different substrate surfaces, while using resistance heating elements, Peltier elements, etc. to drive these thermochromic pigments to change color. However, in such methods, an electronic component can usually only be used to drive uniform color change of an entire area, and if complex and fine color change dynamic effects are desired, the size and complexity of the hardware circuit will greatly increase. The second method of implementing variable color interfaces is to programmably change the appearance of the color of a three-dimensional object using the specific exposure process of a photochromic pigment, however, this method usually requires the object to be placed in a precise optical instrument for exposure for up to 1 minute, which makes it difficult to design and utilize the process of changing the color of the object. In addition to the above methods, other methods of implementing variable color interfaces, such as using fluid materials or light-emitting materials to produce three-dimensional dynamic display surfaces, however, these methods usually constrain the material of the display surface, such as requiring a transparent or light-emitting material surface, which makes it difficult to achieve variable color effects on daily materials. Overall, existing research on variable color interfaces rarely involves key technical processes related to the design and manufacture of variable color process "dynamic effects", and usually does not have the ability to produce variable color effects on complex shape surfaces or daily material surfaces. It is difficult to simulate the color development effect of thermal materials and test the preset effects. SUMMARY

[0048] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0049] The present application will be described below in combination with Figures 1-5 A thermal fluid composite material dynamic effect simulation method is described in the present application, comprising:
[0050] S100, acquiring the geometric structure of different layers, the color temperature mapping of thermochromic paint and other empirical parameters, and performing initialization simulation configuration;
[0051] S200, performing simulation simulation, simulating the flow of thermal fluid in real time, i.e. flow temperature, flow rate and direction, and switching between three-dimensional optical and thermal views to watch real-time simulation results and record them;
[0052] S300, after the simulation simulation is completed, the simulation result analysis is performed according to the output optical and thermal videos with time stamp and the operation log of thermal fluid.
[0053] In the present application, by changing the geometric pattern of the flow channel layer flow channel of the thermal fluid composite material, the material can create multiple color-changing dynamic effect styles in the same area. The dynamic effect styles include:
[0054] Erase: using a compactly arranged flow channel (serpentine or spiral line) pattern, the temperature in the area can gradually change along the direction of the flow channel arrangement, thereby producing the dynamic effect of erasing;
[0055] Diffusion: using a flow channel pattern arranged in a spiral manner, the temperature in the area can change radially from the center of the area to the boundary, or from the boundary to the center, thereby producing the dynamic effect of diffusion;
[0056] Texture: Using flow channel patterns distributed in a non-linear grid fashion, so that the temperature distribution with similar grid patterns is displayed, a texture effect is created;
[0057] Path: Using serpentine flow channels arranged along a given path, the temperature and color move along the same path. When a crossing point is encountered, a bridge flow channel can be designed to connect the crossing flow channels. The path effect can also be implemented using single-line flow channels, however, due to the sparse distribution of the thermal fluid in this case, the temperature distribution gradient can be small, so we recommend using a high-sensitivity thermochromic material (such as liquid crystal ink) as the pattern layer in this case;
[0058] Custom effect: The material can also support custom flow channel structures, expanding the design space of the effect pattern, and creating a pixel-like effect using Hilbert curves; or creating an effect with irregular shapes using growth curves;
[0059] Fade-in and fade-out: It does not depend on any specific flow channel pattern, only needs to ensure that the flow channels are arranged compactly. It relies on the gradual change of the temperature of the fluid and the blur effect.
[0060] Based on different effect patterns, the material can also create variants of the effect pattern in the "continuity" and "directionality" attributes by changing the temperature and direction of the thermal fluid flow.
[0061] "Continuity" refers to whether the effect is continuous or intermittent in space, which is determined by the sequence of temperature changes of the thermal fluid. Each effect pattern has a temperature change in one direction once in the length of a single effect time. Conversely, if we repeatedly raise and lower the temperature at a period less than the length of a single effect time, we can get an intermittent version of the effect. Wide stripe patterns can be observed in both optical and thermal images. If the temperature is changed in a slow and gradual manner, it is likely to achieve an approximately uniform change in temperature within a region, resulting in a "fade-in and fade-out" effect pattern.
[0062] "Directionality" refers to the direction of motion of the effect in space. This attribute only applies to effect patterns with a clear direction of thermal fluid flow, because in these cases, the direction of motion of the effect is determined by the direction of motion of the thermal fluid. By coordinating the direction of motion of the thermal fluid and the change in temperature, two types of cyclic patterns of the effect can be created. Specifically, if the thermal fluid continues to flow after an effect ends, but only reverses the temperature change without reversing the flow direction, the effect will change the color back to the initial state along the original direction of motion, forming a "one-way cycle"; conversely, if the temperature change direction and flow direction are reversed at the same time after an effect ends, the effect will change the color back to the initial state in the opposite direction of the original motion direction, forming a reverse effect, thus forming a "mirror cycle".
[0063] Reference Figure 7 In the present application, the simulation specific process includes:
[0064] Simulation initialization, the structure of each layer of the thermal fluid composite material is abstracted into a single-layer triangular facet grid, the grid structure of each layer in the overlapping area is the same, the equivalent mass m of each particle, the specific heat capacity c of the input material parameters and other parameters are calculated, and the initialization configuration is completed;
[0065] If the simulation is not finished, the time step is increased by Δt;
[0066] According to the thermal fluid flow, the streamline and the cross-sectional area, the distribution of the thermal fluid is updated;
[0067] Based on the FVM method, the heat Q_h absorbed by each particle from the adjacent particles in the same layer is calculated for each grid in each layer;
[0068] Based on Newton's cooling law, the heat Q_v absorbed by each particle from the particles in the adjacent layer is calculated for each grid in each layer;
[0069] Based on the formula Q_h+Q_v=cmΔt, the temperature change of each particle in the time step is calculated for each grid in each layer;
[0070] According to the temperature change of each particle in the surface grid and the color temperature mapping relationship of the surface color-changing pigment, the color of the surface grid node is updated until the simulation is finished.
[0071] Carrying out simulation, real-time simulation of thermal fluid flow, i.e. flow temperature, flow rate and direction, and switching between three-dimensional optical and thermal views to watch real-time simulation results and record, including:
[0072] S101, fluid simulation is performed to calculate the flow process of the thermal fluid in the fluid layer;
[0073] S102, ignoring the fluid dynamic effects of water flow, including density, gravity and viscosity, only considering the set water flow kinematic model;
[0074] S103, for linear water flow, the water flow is simplified as a series of moving segmented heat sources, and the material and heat exchange between the water flow cross sections is ignored;
[0075] S104, for mesh water flow, ignoring the irregular perfusion process of the mesh structure, the water flow is simplified as a mesh heat source with uniform temperature.
[0076] The fluid simulation module is used to calculate the flow process of the hot fluid in the fluid layer. In order to simplify the simulation model, it is assumed that the water flow is laminar, and the fluid dynamics effects of the water flow, such as density, gravity and viscosity, are ignored, and only the following water flow kinematic model is considered: for linear water flow, the water flow is simplified as a series of moving segmented heat sources, and the material and heat exchange between the water flow cross sections are ignored; for the network water flow, the irregular perfusion process of the network structure is ignored, and the water flow is simplified as a network heat source with uniform temperature. For other different geometric flow channel sizes, if the above kinematic model assumptions are met, they can be included in the simulation range.
[0077] The simulation is performed to simulate the hot fluid flow in real time, that is, the flow temperature, flow rate and direction, and switch between three-dimensional optical and thermal views to view the real-time simulation results and record, also including:
[0078] S201, heat transfer simulation is performed to calculate the dynamic change of the surface temperature of the composite material caused by heat conduction;
[0079] S202, ignoring the transverse heat conduction and heat residue between the flow channels, only considering the heat conduction and heat residue along the surface direction of the composite material;
[0080] S203, using the finite volume method to calculate the temperature distribution of the outer surface of the material.
[0081] The heat transfer simulation module is used to calculate the dynamic change of the surface temperature of the composite material caused by heat conduction. Since the thermal conductivity coefficient of the flow channel layer material is low, the transverse heat conduction and heat residue between the flow channels are ignored, and only the heat conduction and heat residue along the surface direction of the composite material are considered. Since the outer surface layer of the material is very thin, the heat conduction is simplified as a two-dimensional problem, and the finite volume method (FVM) is used to calculate the temperature distribution of the outer surface of the material. For the longitudinal layer-to-layer heat conduction, it is calculated according to Newton's cooling law, at this time, the layer-to-layer heat conduction can be expressed by a unified formula:
[0082]
[0083] Where A is the surface area, T1 and T2 are the temperatures of adjacent layers, and h is an empirical coefficient given in Table 1 for the four cases.
[0084] Table 1 Four layer-to-layer heat conduction coefficients
[0085]
[0086] The simulation is performed to simulate the hot fluid flow in real time, that is, the flow temperature, flow rate and direction, and switch between three-dimensional optical and thermal views to view the real-time simulation results and record, also including:
[0087] S301, color change simulation is performed, and color change of the painting layer is calculated;
[0088] S302, the mapping relationship between temperature and color is approximately simplified as one-to-one mapping, and it is assumed that the temperature distribution of the painting layer is consistent with the material surface;
[0089] S303, when a specific color temperature mapping relationship is provided, the program can calculate the color distribution according to the temperature distribution.
[0090] The color change simulation module is used to calculate the color change of the painting layer. The mapping relationship between temperature and color is approximately simplified as one-to-one mapping, and it is assumed that the temperature distribution of the painting layer is consistent with the material surface. Therefore, when a specific color temperature mapping relationship is provided, the program can calculate the color distribution according to the temperature distribution.
[0091] Among all the parameters that need to be preset, the inherent parameters of the material such as heat capacity can be determined theoretically, and the interlayer thermal conductivity coefficient (Table 1) needs to be determined according to experience. In this version, the parameters of the resin are used as the approximate values of the flow channel layer material, because the physical properties of various materials used in the flow channel layer are similar.
[0092] After the simulation simulation is completed, the simulation result analysis is performed according to the output time-stamped optical and thermal video and the operation log of the thermal fluid, specifically including:
[0093] S401, recording the simulation effect during the simulation simulation process;
[0094] S402, the recorded video is time-stamped, and the time-stamped optical and thermal video and the operation log of the thermal fluid are output;
[0095] S403, the simulation result is analyzed more deeply according to the output content.
[0096] The thermal fluid composite material dynamic effect simulation method provided by the application can realize real-time viewing of dynamic effects through simulation simulation, and can be adjusted to improve the display effect.
[0097] Reference Figure 6 The application also discloses a thermal fluid composite material dynamic effect simulation system, which comprises:
