| Abstract: | In this paper we introduce a large eddy simulation program that is developed by our research team for the purpose of wind farm micro-siting.With this program,the flow fields over the obstacles of rectangular,semi-cylindrical and hemispheric shape are computed respectively.The comparison of the simulation average results of the time-varying flow field and the experimental data shows the reliability of our program.Error analysis of computational results and experimental data is made for the future improvement. |
