涡系与湍流场相互作用的统计特性
Statistical properties of an ensemble of vortices interacting with a turbulent field
摘要:
我们开发了一个分析的形式主义,以确定一个系统的统计特性组成的一个系综的涡与随机位置在平面上相互作用的湍流场。我们用路径积分方法计算生成泛函。函数空间是由两部分组成的统计系综,第一部分表示受湍流影响的涡流,第二部分表示由随机放置的涡流散射的湍流场。
英文摘要:
We develop an analytical formalism to determine the statistical properties of a system consisting of an ensemble of vortices with random position in plane interacting with a turbulent field. We calculate the generating functional by path-integral methods. The function space is the statistical ensemble composed of two parts, the first one representing the vortices influenced by the turbulence and the second one the turbulent field scattered by the randomly placed vortices.
