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 k-epsilon 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 k-epsilon turbulence models. The flow structure is also demonstrated using the modified turbulence model.
