| Abstract: | For the radiative transfer problem in irregular three-dimensional non-gray absorbing media,the hybrid finite volume/finite element method was adopted to solve it.The calculating process of the hybrid method was deduced in orthogonal coordinates.Combining the theory of vector and matrix,the finite element equation general composition method coupling boundary condition was given.The radiative transfer of the attitude thruster nozzle expending segment and its interior absorbing media were regarded as the objec... |
