Numerical simulation of two-dimensional moderately rarefied gas flow in domains with complex geometry
V. A. Balashov Keldysh Institute of Applied Mathematics of Russian Academy of Sciences, Moscow
Abstract:
Application of quasi-hydrodynamic equations for simulation of two-dimensional isothermal moderately rarefied gas flows in samples of artificial porous media is considered. Maxwell boundary conditions are used, its approximation and implementation algorithm are suggested. Results of numerical simulation of flows for three samples with different porosities and permeabilities under different averaged pressure are presented. The qualitatively right Klinkenberg slippage coefficient dependence on coefficient of absolute permeability is noted.
Keywords:
quasi-hydrodynamic equations, digital rock physics, rarefied gas, Klinkenberg effect, slip boundary condition.
