An Experimental Study of Pool Fire Characteristics under the Effects of Cross Winds and Baffles
Fire, 2023 The pool fires that occur behind obstructions in a ventilated environment are very different from other wind-blown pool fires. The pool fire formed by fuel leakage in an engine nacelle is a typical example of a pool fire influenced by cross winds and ...
