Numerical Simulation of Confined Vortex Flow Using a Modified k-epsilon Turbulence Model

The turbulent flow in a tangential inlet / tangential outlet vortex tube is numerically simulated using a modified turbulence model. The results are compared to experimental measurements from literature. The modified model shows better agreement with the local tangential velocity measurements compared to the standard and RNG turbulence models. The flow structure is also demonstrated using the modified turbulence model.
