[1Ia06] Virtual solid cell for mimicking porous media in Direct Simulation Monte Carlo method
A novel porous media model called virtual solid cell (VSC) for the Direct Simulation Monte Carlo method will be demonstrated in the meeting. The conventional porous media models with complex geometry can be simplified by a stochastic procedure in the VSC model. Consequently, the VSC model enables one-dimensional simulation of a rarefied gas flow passing through porous media, contributing to a significant reduction in computation time. It also facilitates the treatment of complex porous media with various porosities. Furthermore, the VSC model shows its potential as a new boundary model to describe surface roughness.
