An efficient algorithm of the unified stochastic particle Bhatnagar-Gross-Krook method for the simulation of multi-scale gas flows

چکیده
Abstract The unified stochastic particle method based on the Bhatnagar-Gross-Krook model (USP-BGK) has been proposed recently to overcome low accuracy and efficiency of traditional methods, such as direct simulation Monte Carlo (DSMC) method, for multi-scale gas flows. However, running with extra virtual particles space interpolation, previous USP-BGK cannot be directly transplanted into existing DSMC codes. In this work, implementation is simplified using new temporal evolution spatial reconstruction schemes. As a result, present algorithm similar can implemented efficiently any codes just by modifying collision module.

A generalized Bhatnagar–Gross–Krook model for nonequilibrium flows
The Bhatnagar–Gross–Krook BGK model approximates the collision term of the Boltzmann equation by a single relaxation process from a nonequilibrium state to an equilibrium state. From the BGK model, the Navier–Stokes, Burnett, and Super-Burnett equations can be derived. However, the success of these derived macroscopic equations in the description of highly nonequilibrium flow is limited. In ord...
متن کاملWeighted Particle Variance Reduction of Direct Simulation Monte Carlo for the Bhatnagar - Gross - Krook Collision
Direct Simulation Monte Carlo (DSMC)-the prevalent stochastic particle method for high-speed rarefied gas flows-simulates the Boltzmann equation using distributions of representative particles. Although very efficient in producing samples of the distribution function, the slow convergence associated with statistical sampling makes DSMC simulation of low-signal situations problematic. In this th...

متن کاملRayleigh-Bénard simulation using the gas-kinetic Bhatnagar-Gross-Krook scheme in the incompressible limit.
In this paper, a gas-kinetic Bhatnagar-Gross-Krook (BGK) model is constructed for the Rayleigh-Bénard thermal convection in the incompressible flow limit, where the flow field and temperature field are described by two coupled BGK models. Since the collision times in the corresponding BGK models can be different, the Prandtl number can be changed to any value instead of a fixed Pr=1 in the orig...
متن کاملA Bhatnagar-Gross-Krook Approximation to Stochastic Scalar Conservation Laws
and study its approximation in the sense of Bhatnagar-Gross-Krook (a BGKlike approximation for short). In particular, we aim to describe the conservation law (1.1) as the hydrodynamic limit of the stochastic BGK model, as the microscopic scale ε goes to 0. The literature devoted to the deterministic counterpart, i.e. corresponding to the situation Φ = 0, is quite extensive (see [1], [11], [15],...
