摘要
为了解格子BGK模型的热流体性质,本文研究了13速格子BGK模型,测量了其粘滞系数及热传导系数,模拟值和理论值能很好地吻合.
To understand the thermalhydrodynamic properties of a lattice BGK model, a 13-speeds model is investigated. The coefficients of viscosity and heat conduction in the model are measured. The simulation results are identical with theoretical results.
