The rate of heat release of a free diesel flame was measured with a rapid compression machine which has a compression ratio of 14.7 and a combustion chamber with a diameter of 196 mm and a thickness of 40 mm. Basing on the experimental observations of the high speed photographs of the spray and flame, the authors proposed a phenomenological model for predicting the rate of heat release of the flame. The model consists of three basic models; air entrainment, mixing and combustion model. It was confirmed that the model could successively simulate the rate of heat release of a diesel flame in the quiescent chamber of the rapid compression machine.
