In this paper, to characterize the flow behavior inside a pipe elbow, the RNG k-ε turbulence model with MUSCL discretization scheme is applied to the simulation.

Numerical flow simulation in a horizontal-to-vertical elbow CFD-based erosion prediction model As sketched in Fig.1, the physical configuration of a horizontal-to-vertical elbow is subject to erosion damage.
The standard k-ε model proposed by Launder and Spalding and other usual k-ε models have been tailored for planar shear layers and recirculating flows, while Re-Normalisation Group (RNG) k-epsilon model performs the best in this simulation.
The RNG model can offer improved accuracy in rotating flows such as modeling rotating cavities and is also favored for indoor air simulations.
