| Research Abstract |
We investigated computational models for simulating shallow open channel flows, such as, flows in rivers, seas and lakes. Shallow grid turbulence, an open channel flow with a side cavity, meandering rivers, density mixing current and flows with a horseshoe vortex are employed as test cases. Comparisons between 2D and 3D models and various turbulence models were performed and appropriate models with sufficient accuracy and enough computational efficiency are tuned.
