The Simulation of Three-Dimensional Flow by Using GPU-based MPS Method

چکیده
A modified moving particle semi-implicit (MPS) method based on GPU acceleration technique is applied to simulate three-dimensional (3-D) free surface flow by using our in-house solver MPSGPU-SJTU in this work. In order to validate MPSGPU-SJTU solver, 3-D dam break and sloshing, two typical violent flows with large deformation and nonlinear fragmentation of free surface are simulated. For dam break case, the results of fluid flied, water front, wave height and impact pressure by GPU simulation are compared to CPU calculation, experiment, smooth particle hydrodynamics (SPH) and boundary element method (BEM). The comparison of fluid field and impact pressure among GPU, CPU and experiment is made in sloshing case. The accuracy of GPU solver is verified by these comparisons. Moreover, the computation time of every part in each calculation step is compared between GPU and CPU solvers. The results show that computational efficiency is improved dramatically by employing GPU acceleration technique.

The thin-layer Navier-Stokes equations are solved for two complete missile configurations on an IBM 3090-200 vectro-facility supercomputer. The conservation form of the three-dimensional equations, written in generalized coordinates, are finite differenced and solved on a body-fitted curvilinear grid system developed in conjunction with the flowfield solver. The numerical procedure is based on ...

In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...

For a Czochralski growth of Ge crystal, thermal fields have been analysed numerically using the three-dimensional finite volume method (FLUENT package). The arrangement used in a real Czochralski crystal growth lab included a graphite crucible, heat shield, heating device, thermal insulation and chamber including two gas outlets. We have considered two cases for calculations, which are configur...

Pool and weir is a type of fishway that provides a route for fish to migrate to damupstream. The effective parameters for fish swimming include velocity, water depth andturbulence. Several rubber dams have been under construction in Mazandaran Province, butthe necessary structures have not been built around them yet. When constructing these rubberdams, numerical models can be used to evaluate f...
