本文评估了一个大型太阳能烟囱发电厂的性能。该研究考虑了在南非参考地点特定气象条件下特定参考工厂的性能。采用计算机模拟程序同时求解控制方程和吃水方程。新开发的对流传热和动量方程包括在数值模型和多个模拟进行。结果表明，24小时工厂发电量，同时说明相当大的日常和季节性的功率输出变化。结果表明，植物的发电量是集热器屋顶形状和入口高度的函数。
This paper evaluates the performance of a large-scale solar chimney power plant. The study considers the performance of a particular reference plant under specified meteorological conditions at a reference location in South Africa. A computer simulation program is employed to solve the governing conservation and draught equations simultaneously. Newly developed convective heat transfer and momentum equations are included in the numerical model and multiple simulations are performed. Results indicate 24 hr plant power production, while illustrating considerable daily and seasonal power output variations. It is shown that plant power production is a function of the collector roof shape and inlet height.
