AbstractCTS-0075076Kimmel, Lehigh UniversityRotating convection, in which buoyant and non-inertial forces govern the resulting motion, are of importance in geophysical as well as some technological flows. The computational description of these flows represents a significant challenge and the developing techniques of Large Eddy Simulation (LES) provide a logical method of approach. The PI will use one of the advanced subgrid models: the "estimation model", to attack this complex fluid dynamics problem. The success/failure of these computations will be instructive in evaluating the efficacy of the estimation model.

旋转对流在地球物理和一些技术流动中都具有重要意义。这些流动的计算描述是一个巨大的挑战，而大涡模拟(LES)的发展技术提供了一种合乎逻辑的方法。PI将使用先进的子网格模型之一：“估计模型”来解决这一复杂的流体动力学问题。这些计算的成败将对评估模型的有效性具有指导意义。
