Using a Parallel Spatial/Angular Agglomeration Multigrid Scheme to Accelerate the FVM Radiative Heat Transfer Computation-Part II: Numerical Results

A parallel spatial/angular agglomeration multigrid methodology, employing the full approximation scheme (FAS), is developed to accelerate the finite-volume method for the prediction of radiative heat transfer in absorbing, emitting, and scattering gray media. The methodology for the spatial, angular...

Popis
Shrnutí:A parallel spatial/angular agglomeration multigrid methodology, employing the full approximation scheme (FAS), is developed to accelerate the finite-volume method for the prediction of radiative heat transfer in absorbing, emitting, and scattering gray media. The methodology for the spatial, angular, and combined spatial/angular agglomeration multigrid procedure was analyzed in Part I of this study. In this second part the proposed numerical scheme is validated against benchmark test cases, demonstrating its capability for considerably improved computational performance, especially in problems including scattering media and reflecting boundaries.
