Simulation of Three-Dimensional and Unsteady Lake and Reservoir Flows

在稳定分层湍流的情况下，将完成一个数值计算机代码，并针对已有的基准实验室实验进行测试。该代码基于大涡模拟，其中利用可变的网格细化和分辨率来将子网格湍流效应推向足够小的区域，以验证独立于层结和浮力效应的通用子网格模型。该代码的最终应用是对分层水库和湖泊进行建模，重点是混合和分散。该模型的目的是使用自适应网格方法来产生更准确和更高分辨率的结果，其复杂程度和成本不高于目前现场使用的结果。

A numerical computer code is to be completed and tested against an already available benchmark laboratory experiment for the case of stably stratified turbulent flow. The code is based on a Large Eddy Simulation in which variable grid refinement and resolution is utilized to everywhere push the sub-grid turbulence effects into regions small enough to validate a universal sub-grid model which is independent of stratification and buoyancy effects. The eventual application of the code is to be modeling of stratified reservoirs and lakes, focusing on mixing and dispersion. The purpose of the model is to use adaptive grid methodology to produce much more accurate and high resolution results at a degree of complexity and cost no greater than these now used in the field.
