Gas Dynamic Interactions in Many Body Systems

多体（粒子）之间的相互作用将被研究时，间隙流体是在这样一个低的压力，连续性方程不成立。 在考虑克努森数的整个范围内，提出了描述两个球相互作用的气体动力学方程的解析解。 分子动力学方法，包括时间相关形式主义和广义布朗动力学，用于更复杂的系统的粒子在气体中运动。 这项工作与气溶胶科学和技术有关。

The interactions between multi-bodies (particles) will be investigated when the interstitial fluid is at a such low pressure that the continuity equation does not hold. Analytical solutions to the gas kinetic equations ware proposed to describe the interaction of two spheres by considering the entire range of the Knudsen number. Molecular dynamics methods, including the time correlation formalism and generalized Brownian dynamics, are used for more complex systems of particles moving in gases. The work has relevance to aerosol science and technology.
