Abstract	3D wind field construction is important in many aspects, such as wind energy assessment, wind turbine siting and weather forecasting. The development of Computational Fluid Dynamics (CFD) 3D wind flow over complex terrain and boundary conditions in simulation has been studied intensively over past thirty years. However, the topographical effects has seldom been considered in the 3-D wind field construction in suburban environment. In this paper, 3-D wind field is constructed with consideration of terrain effects. 3-D terrain flowing mesh is built from digital elevation data (DEM) by in house codes. The Reynolds-averaged Navier-Stokes equations are solved by the standard k-ε turbulence model with Ansys Fluent©. The integration between the topographical effects and 3D wind field in suburban environment is investigated. Simulation results of 3-D wind field, wind velocity distributions, turbulence intensity distributions, wind power density distributions and wind profiles are obtained around Purdue University Calumet (PUC) campus. Additionally, the surround building effect and topographical effect are discussed. The simulation results are validated against measurements data.
