Grant-in-Aid for Challenging Exploratory Research
Fire whirl appeared over L-shape fire source is investigated at various scales; one is made by large-scale wind tunnel equipped at Building Research Institute (BRI) and the other is made by small-scale wind tunnel in the lab (Scale factor is five times). It turned out that the existing scale law is not enough to predict the location of the pair of fire whirls. We found the additional scaling law to make this possible and scale model experiment is eventually established for this purpose. Through the small-scale model experiment, flow pattern around the fire whirl is visualized by laser sheet and time-evolution of fire whirl is properly captured. Further study will be continued to investigate the stability in detail.
