Natural ventilation: CFD aerodynamic study about passive extractor and windcatcher
Abstract
Natural ventilation has won popularity in recent times like an energy saving way for buildings. There are two fundamental principles of natural ventilation: natural draft by difference in temperature and wind strength. The article aims to analyze the aerodynamics of windcatcher and wind-extractor by computational fluid-mechanics, optimizing the geometry of these elements, and giving as a result of the work a simplified model to take account aeraulic calculation of air conditioning system. So, It has characterized a collection of wind-catchers; and have developed a guide for geometric design of wind-extractor, also several of them like a result of the work.
