| Abstract: | In order to accurately predict the thermal and structural behavior of throat inserts in solid rocket-motor environments,a fluid-thermal-structural coupling model was established based on CFD code FLUENT and FEM code ANSYS.Fully coupled fluid-solid analysis was performed first to simulate the heat transfer and material erosion process,using the method of whole-field discretization and solution in FLUENT.Subsequently,the structural analysis was carried out in ANSYS based on the resulting pressure and thermal ... |
