Parallel Computing Application on Combustion and Emission Analysis of an Annular Gas Turbine Combustor
Sung, Hong Gye

To analyze the emissions of a turbulent leanpremixed Methane-air combustor, a level set Gequation method has been implemented in the LargeEddy Simulation (LES) framework using parallelpersonal server. The server consists of 36 nodes with12 CPU cores a node. GRI-MECH 3.0 which is acompilation of 325 elementary chemical reactions with53 species, has been used with Presumed-ProbabilityDensity Function (PDF) method. The combustionflames from each injector move extremely dynamicallyand rotate in different directions from adjacentinjectors because the swirl directions of each injectorare opposite to the adjacent injectors. CO has highconcentration on the flame and disappears rapidlyafter the flame due to the lean premixed conditions. NOmole fraction increases continuously after the flameand then is emitted at the exit of combustor.
