Current status and outlook concerning modeling in combustion systems are described. Because of complexity of the phenomena, combustion has hardly been understood in terms of the intrinsic fundamental processes. Thus modeling techniques are indispensable from academic interest as well as practical point of view. Although recent advances in numerical computation made it possible in principle to solve the governing conservation equations for various combustion systems, there are still many difficult problems. In order to overcome these difficulties, considerable simplications and assumptions must be made introducing uncertain phenom enological submodels. In the main part of this review, present state of the art of combustion modeling in practical systems are summarized by dividing into two parts, continuous (furnace and combustor) and intermittent (spark and compression ignition engines) combustion. It should be emphasized that more detailed measurements or diagnostics are necessary to obtain reliable models which can predict practical combustion behaviors. Finally it is concluded that cooperation of investigators in the field of computation and measurement will be advisable for further development.
