Mathematical Models and Computer Simulations Aims and scope

Abstract

A new numerical model is constructed of turbulent wake dynamics behind bodies of revolution in a stably stratified medium based on a semiempirical third-order turbulence model. The employed differential transport equations of all triple correlations of velocity field oscillations, written with allowance for fourth-order cumulants and improved algebraic representations of joint triple correlations of velocity and density fluctuations, enable the comprehensive description of an anisotropic turbulence decay in a far momentumless wake in a stratified medium
