论文摘要
我们使用直接数值模拟的数据库来评估稳定分层流中能量耗散率的参数化。我们表明，基于剪切的配方比常用的基于浮力的配方更适合稳定的边界层。作为派生的一部分，我们探索了几个长度的湍流尺度，并研究了它们对局部稳定性的依赖。
We use a database of direct numerical simulations to evaluate parametrizations for energy dissipation rate in stably stratified flows. We show that shear-based formulations are more appropriate for stable boundary layers than commonly used buoyancy-based formulations. As part of the derivations, we explore several length scales of turbulence and investigate their dependence on local stability.
