Accelerating the Monte Carlo simulation of the Enskog equation for multiscale dense gas flows
Bin Hu, Liyan Luo, Lei Wu
A general synthetic iterative scheme is proposed to solve the Enskog equation within a Monte Carlo framework. The method demonstrates rapid convergence by reducing intermediate Mon…
