In order realistically represent the complex turbulence-chemistry interaction at the partially premixed turbulent lifted flames encountered in the gas turbine combustors, the combined conserved-level-set flamelet approach has been adopted. The parallel unstructured-grid finite-volume method has developed to maintain the geometric flexibility and computational efficiency for the physically and geometrically complex flows. Special emphasis is given to the swirl effects on the flame stabilization of the lean-premixed gas turbine combustor. Numerical results suggest that the present approach is capable of realistically simulating the combustion characteristics for the lean-premixed gas turbine engines and the lifted turbulent jet flame with a vitiated coflow.
