【摘要】 采用计算流体动力学(CFD)方法分析了烟囱对太阳能烟囱发电系统效率的影响。通过对烟囱高度、烟囱形状、烟囱内表面粗糙度和温度对系统的影响分析表明:在其它条件不变的情况下,烟囱高度和直径对系统效率影响最为显著,其次是形状,最后是烟囱内表面粗糙度和温度。更多还原

【Abstract】 Some influence factors of efficiency in solar chimney power plant are studied by using the Computational Fluid Dynamics(CFD) method in the paper.The study shows the height and diameter of chimney are the most important influence factors,next is the shape of chimney,the least influence factors are the roughness and temperature of the chimney inner surface.The purpose of this paper is to deliver some advice for application and development of solar chimney generation system in future.更多还原
