COMPUTATIONAL INVESTIGATION ON MICRO GAS TURBINE ENGINE WITH VARIOUS SWIRLER CONFIGURATIONS
Journal Title: IJSR-International Journal Of Scientific Research - Year 2018, Vol 8, Issue 6
Abstract
In conventional gas turbine engine there are so many difficulties to obtain proper combustion. A swirler is used for mixing air and fuel for combustion and stabilizing the flame. In order to stabilize the flame, the incoming high-speed air must be decelerated to a velocity below the turbulent flame speed. The flame stabilizes along the locus of points where the air velocity is equal to the flame speed. There are so many ways to mix fuel air and stabilize the flame for proper combustion that will not only improve the fuel efficiency by combustion of fuel but also reduces the emission and pollution significantly by creating the internal and central recirculation zone. This paper presents the study of micro gas turbine engine with different configurations of swirlers. The incorporation of swirler can divide stream flow into multiple streams to obtain high turbulence inside the combustor for proper mixing of air with fuel and efficient performance in combustion and also swirler is used to stabilize flame by producing high turbulence. In this micro combustor we use inner and outer annulus to induce turbulence intensity and to stabilize the flame inside the combustor. In this present numerical study, a conventional micro gas turbine engine is considered and the swirler configurations are modified for better swirling performance. Also the porous media is used instead of swirler to improve the mixing performance. The CFD predictions prove that the effect of swirling is completely affected by changing the swirler hole configurations. Also the porous media can be used for better swirling effects.
