均匀气体的直接模拟
Direct simulation for a homogenous gas
摘要:
给出了均匀气体直接模拟的概率分析。一个层次的方程类似的BBGKY层次的减少概率密度推导。通过引入分子混沌假设,导出了类似于玻尔兹曼方程的单粒子几率密度方程和相应的H定理。
英文摘要:
A probabilistic analysis of the direct simulation of a homogeneous gas is given. A hierarchy of equations similar to the BBGKY hierarchy for the reduced probability densities is derived. By invoking the molecular chaos assumption, an equation similar to the Boltzmann equation for the single particle probability density and the corresponding H-theorem is derived.
