Abstract: Windcatchers are known as environment-friendly architectural elements that provide buildings with effective wind-induced natural ventilation. Air shortcircuit is an unintended air path that should be prevented due to the negative impact on the ventilation performance of windcatchers. This study aims to numerically evaluate the effect of five different crosssection shapes of the anti-short-circuit device (ASCD) including triangular, circular, rectangular, elliptical, and straight on short-circuiting reduction in two-sided windcatchers. According to the obtained results, the triangular shape shows the best performance among all cases while the elliptical shape leads to the worst short-circuiting condition in comparison with other shapes.
