Abstract

Understanding physics of heat and mass transfer inside large vertical spaces is a major challenge for high-rise fire safety. Due to the size of a high-rise building, experimental studies based on sub-scaled models play an important role in high-rise heat and mass transfer research. Froude modeling method is probably the most common approach for sub-scaling. It does not consider heat transfer at the building boundaries, and may limit its application in cases where there exists significant heat transfer between smoke and the boundaries. In this presentation, a new modeling method, Froude-Stanton modeling is introduced, in which heat transfer is taken into consideration in the energy balance equation. A case study on a 17-story institutional high-rise building located at the downtown Montreal (Canada), is introduced. The building is sub-scaled 1:100 using the proposed scaling method. Whole-building numerical simulation on the full size and small size buildings are conducted, the results of which are compared.
