Local Entropy Balance through the Shock Wave

抄録

There are various types of bimodal approaches to the shock wave structure. How well the convection and the production of entropy (or the Boltzmann H function) are locally balanced by these approaches through the shock wave in both hard and Maxwellian molecule gas, is investigated based on the Boltzmann transport equation for various upstream Mach numbers. The most successful bimodal approach is found from this point of view. A comparative discussion on other methods than bimodal is added.
