The prediction of turbulent swirling jet flow
A space marching integration procedure is used to solve the Reynolds equations governing the axisymmetric incompressible turbulent swirling jet flow. Turbulence is modelled by the k-\(\epsilon\) model with an isotropic turbulent viscosity. Besides mean velocity field, turbulent properties - such as Reynolds stresses, turbulent kinetic energy and dissipation rate - are obtained and the results are compared with experimental data. Agreement is quite encouraging and shows that the assumption of isotropic turbulent viscosity seems plausible.
