Abstract
We realized the space-time Conservation Element and Solution Element method (CESE) on GPU and applied it to condensation problem in a 1D infinite length shock tube. In the present work, the CESE Method has been implemented on a graphics card 9800GT successfully with the overlapping scheme. Then the condensation problem in 1D infinite shock tube was investigated using the scheme. The speedup of the condensation problem with the overlapping schemes is \(71 \times \) (9800GT to E7300). The influence of different meshes on the asymptotic solution in an infinite shock tube with condensation was studied by using the single GPU and GPU cluster. It is found that the asymptotic solution is trustable and is mesh-insensitive when the grid size is fine enough to resolve the condensation process. It is worth to mention that the peak value of computing reaches 0.88 TFLOPS when the GPU cluster with 8 GPUs is employed.
