CFD analysis of wind blocking vs. venturi effect: a case study in tropical climate

Wind catchers are structures used for natural ventilation using the two basic principles of stack effect and wind induced natural ventilation and has recently attracted a lot of attention due to relying only on the free sustainable energy of wind and hence being able to reduce energy expenditure and...
