Abstract

In order to improve the simulation efficiency of the space environment, a kind of honeycomb thermal shroud is designed. Using the fluid mechanics theory and the finite element method to do the numerical simulation for the fluxion and the heat transfer enhancement of the internal fluid in the honeycomb thermal shroud, this paper analyzes the effects of the structural parameters of the honeycomb thermal shroud on the fluxion and the heat transfer to determine the optimal honeycomb structural parameters. The results are shown as follows: the temperature uniformity can reach ±2K under the load conditions; the depth and spacing of the internal flow of the thermal shroud is an important factor affecting the fluxion and heat transfer in the thermal shroud; it is necessary to consider the heat transfer and resistance problem to determine the optimal thermal shroud structural parameters.; the optimal separation distance of the thermal shroud passage is 75mm and the depth is 10mm.
