AB - The behavior of whirling flame above a pool fire under cross wind was studied  using a small wind tunnel. Whirling flames with different heat release rates  were generated by an experimental rig. Effect of different wind speeds on the  whirling flame was studied by an oil pool of two different diameters. Lateral  images of the whirling flame collected were analyzed. Results show that under  cross flow, the whirling flame was deflected along the direction of incoming  flow. With the increase in wind speed, the deflection angle  increased gradually. The angle also increased with the increase in pool  diameter. When the cross flow increased to a certain value, the flame stopped  swirling, and changed to an irregular shape. The maximum cross wind speed of  the flame that did not stop flame rotation decreased with diameter. Crosswind  with lower speed would raise the temperature of the whirling flame. When the  wind speed was higher than a critical value, the temperature was reduced  because burning rate decreased.
