A numerical investigation is conducted for turbulent flow around trash-racks models using a commercial CFD code, CFX-11. The computations were performed using two standard two-equation turbulence models (the k–ε with a scalable wall-function and the k–ω models). The results show that the mean velocities are reasonably well predicted by both models. However, at higher approach velocity and blockage ratio, the turbulence models, over-predicted the minimum pressure head.
