本研究小组开发了一个应用于风电场微观选址的大涡数值模拟程序,本文介绍了利用该程序分别模拟气流通过方柱、半圆柱和半球等障碍物的流场,并通过比较一段时间内非稳态流场的模拟平均值与实验测量结果,检验了程序的准确性和精确度,同时对模拟结果和实验结果进行了误差分析。
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.
