Abstract
To investigate turbulent combustion phenomena in a gas-turbine combustor, we conduct a numerical simulation of a partially premixed turbulent combustion in a practical combustor. Large-Eddy simulation and 2-scalar flamelet approach are coupled and applied to the unsteady turbulent combustion simulation in the combustor geometry for modeling turbulent and combustion reaction phenomena, and also their interactions. This paper reports an application of the LES to a 1700 degree class of new-Generation gasturbine combustor and discusses their feasibility to the practical combustor design.
