摘　　要：建造了国内第一座小型的太阳能烟囱发电试验装置,并用FLUENT软件对该装置的流场进行了数值模拟,将温度场模拟计算值和试验检测值进行了比较,结果虽有差别,但有相似性。数值模拟结果表明,太阳能烟囱的输出功率及能量转换效率随集热棚面积和烟囱高度的增加而增加。The first small-scale solar power chimney for power generation in our country has been constructed, a numerical simulation of flow field inside the said chimney being carried out, and comparison between calculated value of the temperature field simulation and measured value in the test being made, the results having difference, but having similarity. The results of simulation show that the output power and energy conversion efficiency of the said chimney increase along with increasing the area of heat-collecting shed and the height of the chimney.
