The Effect of Plan Size in Wind Catcher on its Ventilation Rate
Wind catchers/towers systems were employed in buildings in the Middle East for many centuries and they are known by different names in different parts of the region. Their application in the hot arid region of the Middle East is to provide for natural ventilation/passive cooling and hence thermal comfort, exploiting, particularly, night-time ventilation strategy. They can be beautiful objects, feasible architectural feature additions to buildings and are inherently durable. This paper aims to find out the best plan geometry and plan size in order to increase the ventilation rate by 3-D computational fluid dynamics (CFD) simulations with comparing volume flow rate in different four-sided wind catcher with different geometry and plan size.
