Abstract

Swirling flow generates recirculation and provides better mixing and turbulence. To study the flow behavior and its effect in combustion chamber, CFD simulation is performed and recirculation zone and shape of the flame region is found out for axisymetrical 12 vane swirler with 50° vane angle. Three dimensional velocities for swirling flows are found out by means of computational fluid dynamics (CFD), for producing Recirculating Zone to control the length & stability of flame in the Gas Turbine Combustor. The core objective of this study is to present the effect of swirler geomentry and inlet conditions on recirculation length. The flow through 12 vane 50 deg swirler is investigated by using ANSYS CFX software. Present work gives complete behaviour and knowledge about recirculation zone & effect of guide vanes.
