Abstract

Based on an algebraic model of Reynolds stresses and fluxes, a numerical model of the dynamics of a flat localized region of turbulent perturbations of non-zero buoyancy in a linearly stratified medium was constructed. The evolution of a weakly heated turbulent spot was considered. Presence of non-zero buoyancy leads to increase in the geometrical dimensions of the turbulent spot and generation of internal waves of greater amplitude.

线性分层介质中弱热湍流混合区动力学的数值模拟

摘要

基于雷诺应力和通量的代数模型，建立了线性分层介质中非零浮力湍流摄动平面局部区域动力学的数值模型。考虑了弱加热湍流点的演变。非零浮力的存在导致湍流斑的几何尺寸增加并且产生更大振幅的内波。
