Abstract

• Swirl vector based method is proposed to identify the core region of indoor tornado. • Centre of indoor tornado keeps changing along the vertical travel direction. • Tornado core region size changes significantly along the vertical travel direction. • The best contaminants removal is achieved at lift angle of 20° in this study. • Optimum lift angle range from 10° to 20° is recommended for future study.
