本文建立了太阳能上升式电站集热器在太阳辐射作用下的定常无粘流计算模型。结果得到了一组描述太阳辐射转化为集热器气流热流的非线性方程。采用迭代格式求解质量流量和温度方程，并编制了相应的计算机程序。将仿真结果与曼萨纳雷斯样机的实验数据进行了比较，表明两者之间具有很好的一致性。日本选定地点的计算功率也被演示了太阳能上升气流发电厂的潜在应用。
In this paper we develop a theoretical model for calculating the steady inviscid flow subjected to solar radiation at the collector of a solar updraft power plant. The result was a set of nonlinear equation describing the transformation of the solar radiation into heat-flux of the collector airflow. Iterative scheme was employed in order to solve the equation for mass flow rate and temperatures, for which computer codes were developed. A comparison of simulation results with the Manzanares prototype experimental data was performed; demonstrating good agreement between the two. Computed power for selected locations in Japan was also demonstrated for potential application of a solar updraft power plant.
