Embodiment Construction

[0056] The present invention will be further elaborated below in conjunction with embodiment.

[0057] Such as figure 1 Shown is a schematic diagram of sweat cooling. The spherical part in the figure is the sweating end of the porous medium. The external main flow flows from left to right, and the coolant seeps out from the porous medium and mixes with the main flow. To simulate this problem, the flow outside the head and the pore flow in the porous media need to be simulated. The external mainstream flow is simulated by the mainstream calculation module, the pore flow in the porous medium is simulated by the porous medium calculation module, and the seepage interface is coupled through the method of the invention.

[0058] figure 2 The topological schematic diagram of the flow process simulated by this method includes a coupling control module, a mainstream calculation module, and a porous medium calculation module.

Abstract

The invention relates to a distributed multi-physical-field coupling control system for simulating sweating cooling. When sweating cooling numerical simulation is carried out, the difference between flowing inside a porous material and flowing around the outside of a structural component is large, simulation is difficult to achieve under a set of frame due to the difference of used numerical technologies, and the precision and efficiency of a loose coupling simulation mode based on file exchange in engineering need to be improved. According to the method, the sweating cooling simulation coordination cooperation level is improved by determining the effective communication coupling model and the tight coupling boundary condition, and different calculation modules can run in respective address spaces and perform real-time tight coupling calculation during sweating cooling simulation, so that the simulation precision and the calculation efficiency are improved.

Description

technical field [0001] The invention relates to the fields of computational fluid dynamics, engineering thermophysics, and high-performance parallel computing, and relates to a distributed multi-physics field coupling control system for simulating sweat cooling, which is applicable to the engineering of computational fluid dynamics method multi-physics field simulation sweat cooling process application. Background technique [0002] Porous sweating cooling technology refers to making materials into porous material structural parts. During the working process of the parts, the coolant permeates and evaporates from the "pores" inside the structural part materials to the outside under high pressure, thereby taking away the heat of the parts and cooling the structure . The working mechanism of porous sweat cooling is that when the sweating agent flows through the interior of the porous material part, it can carry the heat of the part, thereby changing the internal temperature f...
