Numerical and experimental analyses were carried out with respect to the relationships among the change of diffusion and combustion processes, the location of fuel injection port and the distribution profiles of surrounding air flows. With the object of simulating the complex flow field, a calculation was made under the conditions of three inlets using velocity profiles measured at respective inlets. Effective viscosity expressed in a similar formula to Prandtl one and numerical analyzing procedures of effective difference, finite reaction rate and of combustion efficiency were introduced to improve the applicability and the convergence characteristics of the calculation. The calculation results agreed qualitatively with the experimental ones, and it was concluded that the diffusion rate of fuel is significantly influenced by the fuel supplying position and the surrounding air flows.
