 March 11, 2002, 08:55 Re: Modelling fire in engine #2 tingguang Guest   Posts: n/a How much fuel is involved? What is the burning area? What kind of engine? fuel and Sizes? You are asking a question with no solid bases. So your question is difficult to answer. Tingguang

The heat of combustion is usually accessible in any fire dynamics book. The dimension is over-all surface. Assume all surface is involved in fire, then total surface area (except the bottom) times mass burning rate times Heat of combustion, you will get firesize. Assume there is no air flow around. You can find some parameters at, or others. D.Drysdale, An Introduction to Fire Dynamics, 1995 Tingguang
