| Abstract: | Temperature field on flow and heat transfer process for composite nozzle was simulated based on fluid-structure coupled method.While the interface program of computational fluid dynamics(CFD) and finite element method(FEM) were complied,the temperature load and mechanical data transfer was realized rapidly.Then a strategy of thermo-structure coupled computation for composite nozzle was put forward.Direct constraint procedure solved the boundary nonlinear problem caused by carbonization of component interfac... |
