平行化稀薄热气流场求解器 ultraSPARTS
ultraSPARTS
ultraSPARTS (ultrafast Statistical PARTicle Simulation Package), is a particlebased C++ objectoriented parallel DSMC simulation code designed for efficiently solving gas flow problems with rarefaction and strong nonequilibrium. This software employs the direct simulation Monte Carlo (DSMC) method for directly solving the Boltzmann equation statistically. It can deal with rarefied gas flows with complex geometry using 2D/2Daxisymmetric/3D hybrid unstructured grid. The package has been applied for modeling general rarefied gas dynamics such as hypersonic nonreacting and reacting gas flows, vacuum pumping flow, satellite plume impingement, MEMS/NEMS gas flow, comet gas/dust plume (paper reference 19), and PVD deposition (OLED, CIG, Ebeam, etc.), to name a few.
Several advanced computational techniques are used to reduce computational time, which include parallel computing using domain decomposition through message passing interface (MPI), variable timestep scheme (VTS) for reducing number of iteration towards steady state, transient adaptive subcell scheme (TAS) for improving collision quality, virtual mesh refinement (VMR) for resolving regions with large properties gradient, conservative weighting scheme (CWS) for treating trace species efficiently. In addition, a special technique, named as DREAM (DSMC Rapid Ensemble Average Method), is developed to reduce the statistical scatter from unsteady DSMC simulations.
In addition, for dealing with complex nonequilibrium flow problems, several important physical models are included in ultraSPARTS. They include different molecular models (HS/VHS/VSS) for reproducing viscosity and diffusivity of gases, no time counter (NTC) for treating collision probability efficiently, multispecies, translationalrotational energy exchange, translationalvibrational energy exchange, total collision energy model (TCE) for dissociation and exchange reactions [Bird, 1976], threebody collision model for recombination reaction [Boyd, 1992], surface reaction/deposition, pressure/mass flow controlled boundary conditions and pumping boundary conditions for internal gas flows, periodic boundary conditions and inclusion of gravity effect.
