Description of Turbulence in Terms of Lagrangian Variables

摘要: Publisher Summary This chapter reviews that the method of describing turbulence in terms Lagrangian variables is giving statistical characteristics state an “indicator” system. The each indicator determined by its coordinate x and velocity v. consideration track a single may present valuable information on properties flow form distribution function φ(x, v). discusses it makes possible to obtain all one-point some turbulent diffusion also. description with two indicators similar leads double-distribution two-point related it. conditional φT(x, v) principal characteristic motion variables, such as probability selected particle, which at initial moment has xo vo, having after certain period time T
