论文摘要
我们提出了一种新的ES-BGK模型，用于双原子气体，该模型可以通过Landau-Teller和Landau-Teller和牛仔裤放松方程式给出，可以进行翻译旋转和翻译振动的能量交换。该模型与DSMC求解器中通常使用的振动和旋转碰撞数的一般定义一致。事实证明，它可以满足H理论并给出正确的运输系数，直到体积粘度。
We propose a new ES-BGK model for diatomic gases which allows for translational-rotational and translational-vibrational energy exchanges, as given by Landau-Teller and Jeans relaxation equations. This model is consistent with the general definition of the vibrational and rotational collision numbers that are also commonly used in DSMC solvers. It is proved to satisfy the H-theorem and to give the correct transport coefficients, up to the volume viscosity.
