The assessment of the performance of a windcatcher system using computational fluid dynamics

A numerical study of assessment of the performance of a windcatcher using CFD is presented in this paper. A 500 mm square windcatcher system connected to the room has been modeled for different wind speeds in the range of 0.5-6 m/s and four different wind directions. The numerical results agree with the published experimental results of a wind tunnel experiment. The windcatcher system is found to be an efficient way to channel fresh air into the room.
