Saeed Salehi

Researcher at Fluid Dynamics

My research focus is to develop, in OpenFOAM, the required methods that are needed to study transients in hydro turbines. That involves the simultaneous mesh deformation due to guide vanes that change their angle at the same time as a part of the computational domain is rotating. The developed methods can be used to do in-depth studies of the turbulent flow features encountered during transient operation of hydraulic turbines. My research interests are:• Computational Fluid Dynamics • OpenFOAM • Turbulence Modeling • Turbomachinery • Heat Transfer • Uncertainty Quantification • Robust Optimization
