Embodiment 1
[0032] Place the confocal elliptical dual layer nuclear housing structure in the background matrix, applied the temperature gradient and potential gradient of the horizontal and vertical direction, and set up a control group (the elliptical nucleation that will be coated without a double-layer invasive cloak is placed in the background matrix. Middle), in order to compare the full direction of thermoelectric stealth function of the stealth cloak. image 3 Full-directional thermoelectric stealth cloak in the controversial ellipse double core housing structure [ image 3 (b)] and the control group [ image 3 (a)] Workpiece diagram. Among them, the background matrix is formed of a 36-layer alternating layered structure, an odd layer and an even layer of layered structural substrate portion employ a 6061 aluminum alloy, an odd layer, and an even-layer layer-like structure. Air, it is necessary to note that the matrix portion of the odd layer and the even layer-like structure and the ma...

The invention discloses an omni-directional thermal-electric invisible cloak with a double-layer elliptical core-shell structure and a design method of the omni-directional thermal-electric invisible cloak. The thermal-electric invisible cloak comprises a confocal elliptical core area representing an invisible area, a double-layer confocal elliptical shell area representing the invisible cloak and an outermost background matrix from inside to outside, and the confocal elliptical core area, the double-layer confocal elliptical shell area and the outermost background matrix are combined in different heat flow and current directions. And the heat conductivity and the electric conductivity of the background matrix are consistent with the anisotropic equivalent heat conductivity and the anisotropic equivalent electric conductivity of the confocal elliptical double-layer core-shell structure. According to the omnidirectional thermal-electric invisible cloak, external heat flow and current in any direction can be prevented from entering an invisible area, the temperature and potential gradient of the area is zero, disturbance of a temperature field and an electric field in a background matrix cannot be caused by the invisible cloak, and the omnidirectional invisible function of the thermal field and the electric field is achieved.
Description
Technical field [0001] The present invention belongs to the field of super material technology, which relates to a full direction thermal-electric blast cloak in a double-layer elliptical core shell structure and its design method. Background technique [0002] Super material achieves special functions that are not available in some common materials by designing material parameters and structural features. For material design, it is usually achieved by coordinate transform and neutral inclusion. That is, special physical field control functions are achieved by designing material parameters of some areas. For example: stealth function, aggregation function, camouflage function, detection function, etc. As the research further in-depth, super materials for multi-physical field control functions gradually caused interest in researchers, ie, through a super material, simultaneously controlling multiple physics. This can integrate the device of the same control function in different p...
