Numerical simulation of topographic effects on wind flow fields over complex terrain
نویسندگان
چکیده
This study addresses the issues pertinent to both the topographic effects on wind flow fields over complex terrain and the accuracy of computational fluid dynamics (CFD). The numerical simulations using isotropic eddy viscosity and wall functions are conducted based on the numerical solutions of the incompressible, nonisothermal, steady-state turbulent flows, in which a regional computational model of a hilly island in Hong Kong has been constructed and the computational results are compared with the experimental data of a boundary layer wind tunnel testing and the in-situ measurements from a remote sensing facility (Doppler radar wind profiler system) at Cheung Chau (CCH) weather station in the island.

It is highly important in Japan to choose a good site for wind turbines, because the spatial distribution of wind speed is quite complicated over steep complex terrain. We are developing the unsteady numerical model called the Research Institute for Applied Mechanics, Kyushu University, COMputational Prediction of Airflow over Complex Terrain (RIAM-COMPACT). The RIAMCOMPACT is based on the larg...
