Driven by stack effect, smoke often spreads across a building through shafts, which becomes a major challenge for high-rise fire protections. It is therefore important to conduct research on the smoke movement inside high-rise shafts, for which scale modeling based on experiments in sub-scale models of full-size buildings is an important technique. In this paper, a new scale modeling method is developed based on a group of new dimensionless numbers based on the conservations of both heat transfer and mechanical energy for mechanical and natural venting systems of high-rise shafts.
