论文摘要
讨论了椭圆形统计模型的熵特性，PRANDTL编号PR低于2/3。尽管2/3是h定理无条件持有的PR的下限，但表明该定理仍然容纳甚至对于$ \ mathrm {pr} <2/3 $，但规定应力张量的各向异性满足某个标准。该标准的实际耐受性是通过强烈的正常冲击波和COUETTE流动问题来数值评估的。还进行了几个移动的板测试。
Entropic property of the Ellipsoidal Statistical model with the Prandtl number Pr below 2/3 is discussed. Although 2/3 is the lower bound of Pr for the H theorem to hold unconditionally, it is shown that the theorem still holds even for $\mathrm{Pr}<2/3$, provided that anisotropy of stress tensor satisfies a certain criterion. The practical tolerance of that criterion is assessed numerically by the strong normal shock wave and the Couette flow problems. A couple of moving plate tests are also conducted.
