- Abstract:
- The fluid dynamics software Fluent, structured grids and RNG k-?着 turbulence model are used in this paper to research the temperature field distribution around the nozzle with high-temperature heat shield and on the high-temperature heat shield of an engine under the condition of the ground hot test. The calculation results agree well with the experimental results. The results show that, under the condition of the ground hot test of propulsion system, the temperature of all parts of the high-temperature heat shield is within their heat tolerance, and the high-temperature heat shield can effectively isolate the convection and radiation of engine plume and can avoid the propulsion system components around the engine from heating of high-temperature gas.
