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.
