Abstract
A variety of studies regarding the properties of the fire plume in the crosswind were reported from the viewpoint of the spreading prevention in the town area and in the tunnel. When fire experiments are done to understand the structure of a minute flow of the fire plume in the crosswind, it is difficult to examine the properties of the fire plume strictly because of various restrictions. It was analyzed to understand the properties of the fire plume with CFD technique and could be reproduced counter-vortex-pair (CVP) in high temperature area and wall-vortex along the floor. And the properties of two kinds of whirlpool were examined and the relation between them was considered.
