Computational and Cold Flow Analysis on Swirler at Vane Angle 55° & 62° Amit Kumar

Abstract

This paper brings the computational study on geometric swirler of outlet vane angle of 55° and 62° for aerodynamic flow properties and cold flow analysis to be done. At mass flow rate of 0. 3 to 0. 4 kg/s and equivalence ratio are 0. 6 to 0. 7 ,the cold flow study on CFD (computational fluid dynamics )analysis in swirler is done at 55° and 62° are respectively of outlet vane angle and inlet vane angle are usually zero. Also will have found aerodynamics and geometric flow properties in swirler at 55° and 62° vane angles, the swirler numbers are 1.2 and 1.4 respectively is calculated. So purely CFD analysis of aerodynamics properties of flow in swirler at various vane angle(such as 55° and 62°) is investigated and to be designed improvement of swirler with high efficiency of aerodynamics mixing of air and fuel. To support experimental design with CFD analysis will be the key role to predict the improvement of performance and efficiency of swirler.
