A Stratified Turbulence Formulation And A Turbulent Inflow Boundary Condition For Large-Eddy Simulation Of Complex Terrain Winds, Clancy Umphrey
A Stratified Turbulence Formulation And A Turbulent Inflow Boundary Condition For Large-Eddy Simulation Of Complex Terrain Winds, Clancy Umphrey
Boise State University Theses and Dissertations
There has been an increased interest to forecast winds over complex terrain under realistic stability conditions using spatial resolutions that are much finer than the current practice. This goal is realizable thanks to the computational power of graphics processing units (GPUs). This thesis investigates an immersed boundary (IB) formulation and a turbulent inflow boundary condition within a multi-GPU parallel incompressible wind solver. Katabatic flows over a sloped complex terrain surface under stable stratification remain to be one of the least understood subjects in atmospheric turbulence. Prandtl’s analytical solution for laminar katabatic flow is used to develop an IB formulation to …
