Consistent BGK models for inert mixtures are compared, first in their kinetic behavior and then versus the hydrodynamic limits that can be derived in different collision-dominated regimes. The comparison is carried out both analytically and numerically, for the latter using an asymptotic preserving semi-Lagrangian scheme for the BGK models. Application to the plane shock wave in a binary mixture of noble gases is also presented.

惰性混合物的BGK模型：比较和应用

首先对惰性混合物的一致BGK模型进行了比较，然后比较了它们的动力学行为，然后与可以在不同的碰撞主导状态下得出的流体动力学极限进行了比较。对于后者，使用BGK模型的渐近保留半拉格朗日方案，在分析和数值上进行了比较。还介绍了在稀有气体的二元混合物中对平面激波的应用。
