摘　　要：根据太阳能热风发电系统的工作特点,建立其数值分析模型,对系统的能量流进行分析。以西班牙原型电厂为例进行数值模拟,探索太阳辐射强度和环境温度对系统性能的影响。将数值计算和西班牙试验数据进行了比较,结果具有良好的一致性。预测出太阳光辐射强度及环境温度和太阳能热风发电系统集热器进出口温差及由集热器出口到烟囱进口的系统转换段压差的影响关系。为太阳能热风发电系统的设计提供技术支持。Using the solar chimney prototype in Spain as an example, a numerical study was performed to explore the effect of the solar irradiance and ambient temperature on performance of the system. The simulated values were compared with the measured values of Spain. The results show reasonable agreement with each other. Additionally, the calculation estimate the effect of solar radiation and ambient temperature on the temperature difference of inlet and outlet in collector and the pressure difference of collector-to-chimney transition section. The research provides technological support to design the solar chimney power system.
