已开发的太阳能烟囱的分析，特别是针对一个全面的分析和数值模型，它描述了太阳能烟囱的性能。该模型被开发用于估计太阳能烟囱的功率输出，以及检查各种环境条件和结构尺寸对功率输出的影响。从数学模型的结果与实验结果进行了比较，该模型进一步用于预测大型商业太阳能烟囱的性能特性。结果表明，烟囱高度、涡轮机压降系数、集热器直径和光学性能是太阳能烟囱设计的重要参数。
An analysis for the solar chimneys has been developed, aimed particularly at a comprehensive analytical and numerical model, which describes the performance of solar chimneys. This model was developed to estimate power output of solar chimneys as well as to examine the effect of various ambient conditions and structural dimensions on the power output. Results from the mathematical model were compared with experimental results and the model was further used to predict the performance characteristics of large-scale commercial solar chimneys. The results show that the height of chimney, the factor of pressure drop at the turbine, the diameter and the optical properties of the collector are important parameters for the design of solar chimneys.
