In this paper, in order to 3D investigation non-premixed flameless oxidation, large eddy simulation model using OpenFOAM software is applied. In this context, finite volume discrete ordinate model and partially stirred reactor are applied in order to model radiation and the combustion, respectively, and the full mechanism GRI-2.11 is used to precisely represent chemistry reactions. The flow field is discretized using the volume method and PISO algorithm coupled the pressure and velocity fields. The results are compared with Mancini’s experimental data. After ensuring the accuracy of the simulation method, behavior of combustion is examined using fuel injection with an angle into the combustion chamber. The results explain using fuel injection with an angle into the combustion chamber, the net rate of reaction and entropy generation increase and combustion temperature decreases.
