Dynamic modelling of a wind catcher/tower turret for natural ventilation

Experimental and theoretical investigations along with CFD modelling considerations are discussed in this paper to evaluate the performance of a square section wind catcher/tower turret system for natural ventilation.The modelling results tally with the experimental results at lower wind speeds. Wind catchers are innovative techniques, their performance greatly depends on wind conditions. They should be designed as an integral part of the design of the HVAC system in an hybrid or mixed mode operation.
