During this module, you will build a strong understanding of unsteady turbulent flow and the numerical approaches that apply to such cases. You will also learn about advanced simulation techniques applied to viscous flows, turbulence modelling and unsteady flow simulation techniques in CFD. Apart from simulation approaches, this module provides a deep insight about numerical flow solving techniques such as discretization of RANS equations using Finite Volume and Finite Difference techniques, time integration schemes (implicit and explicit) for unsteady flow, one and two- equation turbulence modelling techniques (Spalart-Almaras, k-epsilon and k-omega) and wall functions and you will learn about advanced Post-Processing of CFD problems. As an important part of CFD simulation, this module will also include advanced grid generation schemes, turbulent flow grid requirements and grid movement scheme.
