## Abstract

In turbulent combustion fields, local heat release takes place and intense fluctuation exists in temperature, concentration and density as well as in flow velocity. These condition makes it very difficult to measure and understand phenomena in actual combustors precisely. Therefore, the numerical prediction of turbulent combustion is of great technological use. Considerable progress has been made in recent years in the modeling technique of combustion fields with the development of computers, and then, the present group research selected the modeling of non-premixed combustion flows as one of the main subjects.
