摘　　要：根据太阳能热风发电系统的工作特征,以内蒙古乌海金沙沙漠太阳能热风发电系统为模型,模拟计算了不同形式的太阳能热风发电系统;对比不同系统内的气流分布,研究讨论了风压对气流流动和气流速度大小的影响。模拟结果表明:半圆形集热棚系统更具优势,其利用率较高,塔囱底部的平均气流速度可达24.38 m/s。该研究分析为乌海金沙沙漠太阳能热风发电站的建设提供了技术指导。According to the working characteristics of solar thermal wind and chimney power system,the different forms of the system is simulated with the desert solar thermal wind and chimney power system in Wuhai of Inner Mongolia as the model.By contrast with the different distributions of the air flow in the system,it studied the influence of wind pressure on the flowing and the velocity of air flow.The results are as follows： the semi-circular collector system shows its advantages and its utilization ratio is higher.In addition,the average flow speed at the bottom of the chimney is up to 24.38 m/s.This conclusion will provide technical guidance for the construction of solar thermal wind and chimney power system in the desert of Wuhai.
