Abstract
A numerical study of the flameless combustion process was performed to investigate the influence of turbulent mixing intensity on the combustion process and NO_x formation. The model is based on the representation of flameless combustion by a network of ideal reactors such as perfectly stirred reactor (PSR) and partially stirred reactor (PaSR). The computational results demonstrate that the combustion process as well as the NO_x formation are very sensitive to the mixing intensity. However, the total NO_x emission after complete combustion are seen to be only slightly influenced by the mixing intensity.
