The Numerical Simulation of Swirl Jet Characteristic

Abstract:

This paper studied the velocity distribution of swirling jet through employing the Fluent software to simulate the three-dimensional flow field of swirling jet. By compared the simulation results, the axial, radial, tangential velocity and non-dimensional distribution of swirling jet, and the effects of different swirl intensity on the dimensionless velocity and quantity of reflux can be obtained. Research shows the angular velocity is constant, and different swirl intensity dimensionless reflux along the axial section is similar, and so is the dimensionless velocity distribution.
