| Abstract: | A multi-field coupled computing platform using multi-zone iteration is developed to solve conjugate heat transfer problems.Based on the element features of the finite element method(FEM) and finite volume method(FVM),a local conservative remapping method is presented for thermal flux and aerodynamic load interpolation.Shared memory is employed for faster data exchange for the general FEMs/computational fluid dynamics(CFD) software.The problems of conjugate heat transfer for a cooled converging-diverging noz... |
