Study on ventilation in double-skin facades by numerical simulation


Journal Article

The ventilation in double-skin facades was studied by using computational fluid dynamics (CFD) modeling and wind tunnel test. It was shown that the Subgrid-scale (SGS) model of large eddy simulation correctly predicted wind field in this case. The rate of ventilation for corridor double-skin facade and box facade were compared. Given that ventilating condition is met, box facade is preferable to corridor double-skin facade, in terms of dwelling quality. Multi obliquity and different approaching flows models were utilized to investigate the effects of shutter obliquity on ventilation. Shutters were shown to have an air-oriented effect to certain extend, and the optimal obliquity is near 45° in all different wind directions.
