Minimal number of discrete velocities for a flow description and internal structural evolution of a shock wave

Jae Wan Shim

摘要:

流体流动是由虚拟粒子跳跃均匀分布的节点与一个给定的有限组离散速度。我们强调,存在一个虚构的粒子之间的一个节点的集合中的离散速度是由概率。我们描述了一个可压缩的热流的精度水平的纳维-斯托克斯方程的25或33离散速度的二维空间和执行模拟调查内部结构的冲击波的演变。

英文摘要:

A fluid flow is described by fictitious particles hopping on homogeneously distributed nodes with a given finite set of discrete velocities. We emphasize that the existence of a fictitious particle having a discrete velocity among the set in a node is given by a probability. We describe a compressible thermal flow of the level of accuracy of the Navier-Stokes equation by 25 or 33 discrete velocities for two-dimensional space and perform simulations for investigating internal structural evolution of a shock wave.
