The objective of this investigation is to develop a computer code and an  LES algorithm to simulate turbulent flows in a gas-turbine combustor. A full Navier-Stokes solver has been written with subgrid-scale model  (SGSM),passive scalar transport, and subgrid-scale scalar flux implemented.Currently, heat-release in case of nonpremixed combustion is  being implemented.
