Construction of collision model of diatomic molecules (2nd report, Construction of the model and its verification)

In the 1st report, we made some calculations to obtain data in order to construct a model for collision of diatomic molecules. Consequently, we found that the energy transfer is distributed without a characteristic relation to the direction and orientation of the rotational vector, and that both the energy transfer and collisional cross section strongly depend on the initial translational and rotational energy. In this 2nd paper, we constructed a collision model for diatomic molecules using these data. To make sure of its validity we calculated equilibrium state, viscosity coefficient, heat conductivity, diffusion coefficient and normal shock wave by the DSMC method using our model and compared these results with other theoretical and experimental results. Consequently, we found that the diatomic rarefied gas flows can be simulated very well using our model.
