Abstract

The invention discloses a method for reconstructing the flow field in a channel based on a structured grid. The method is used to reconstruct the flow field including the temperature field, pressure field and Flow field data including velocity field. The present invention converts the flow field data of the flow heat transfer model into a matrix form, establishes a GAN network to realize the reconstruction of the flow field data, and realizes low time cost, low calculation cost, and complete and effective flow at low economic cost. field reconstruction techniques. The invention is fast in calculation and easy to change, and can replace CFD technology to optimize the design of heat exchange devices; it can obtain complete temperature field, pressure field and velocity field data, which is beneficial to data processing and research on the overall flow heat transfer situation, compared with Sophisticated experimental methods have great advantages.

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...
