To better simulate hydrocarbon, CO combustion and pollutant formation in turbulentreacting flows, a new second-order moment model of turbulent gas combustion is developedbased on the combination of a second-order moment closure with the concept of a simplified PDF.

In this article the second-moment closure based on the GLM was investigated in the environment of a strongly swirling turbu-lent flow.

A numerical simulation of a bluff-body stabilized nonpremixed flame has been performed with second-moment turbulence closure (SMTC) models.
