Abstract

The invention discloses an intra-channel flow field reconstruction method based on a structured grid. The method is used for reconstructing flow field data including a temperature field, a pressure field and a speed field from known geometrical parameters, boundary conditions and fluid parameters of a flow heat exchange model. According to the invention, the flow field data of the flow heat exchange model is collected and converted into a matrix form, the GAN network is established to realize reconstruction of the flow field data, and a complete and effective flow field reconstruction technology with low time cost, low calculation cost and low economic cost is realized. The method is quick in calculation and easy to change, and can replace a CFD technology to optimize the design of the heat exchange device. Complete temperature field, pressure field and speed field data can be obtained. Data processing is facilitated, the overall flow heat exchange condition is studied, and the methodhas great advantages compared with a complex experimental method.

Description

technical field [0001] The invention belongs to the technical field of flow heat exchange, and in particular relates to a method for reconstructing a flow field in a channel based on a structured grid. Background technique [0002] In the field of traditional flow heat transfer, there are generally two ways to obtain a flow field information, one is to use a computer to perform CFD numerical simulation, and the other is to conduct experimental tests. In recent years, numerical simulation and experimental testing have achieved different degrees of development and progress. Experimental research methods are gradually developing in the direction of infrared imaging and transient test analysis. On the one hand, the experimental cycle is shortened, and on the other hand, the degree of visualization of the flow field data of the experimental test is gradually improved. Numerical simulation has greatly facilitated the study of flow and heat transfer with the continuous improvement...
