Abstract

The Helmholtz equation is solved using the lattice-Boltzmann technique for a d2q9 lattice velocity scheme. We assumed a distribution function that satisfies the lattice-Boltzmann equation, and its average on cell gives account for the scalar field that solves Helmholtz equation. The method relies on the definition of the second moment of the distribution. We obtain the classic interference behavior for several sources.

用格-玻尔兹曼技术求解亥姆霍兹方程
采用d2q9晶格速度格式的晶格-玻尔兹曼技术求解了亥姆霍兹方程。我们假设一个满足格-玻尔兹曼方程的分布函数,它在单元上的平均值解释了解亥姆霍兹方程的标量场。该方法依赖于分布的第二矩的定义。我们得到了几种源的经典干涉行为。
