Large Eddy Simulation (Les) of Effect in Swirl Number to the Efficiency of Gas Turbine Combustion

Authors: Farid Viko Bhaskarra, Gunawan Nugroho

A good mixing process are required in designing gas turbine combustor. Numerical simulations using Large Eddy Simulations are well suited to address these issues. In this study, a numerical simulation of non reacting flow in gas turbine combustor was performed. There were 5 variations of swirler’s angles (50 , 150 , 200 , 250 and 300 ). Perfomances of these new swirler were investigated. The main target of this investigation is to get the effect of swirler’s angle to combustion recirculation zone. The results show that the longest flame stagnation point of 45,26022 mm was obtained at 250 of swirler’s angle.
