CFD analysis of cross-ventilation of a sheltered building: Comparison between SRANS and LES

摘要

This study shows that SRANS models fail to predict the mostimportant features of cross-ventilation such as windward andleeward jets. It is found that the high accuracy of LES is attributedto the reproduction of the anisotropic velocity fluctuations ofcross-ventilation flow around and inside the target building.
