Started with brief introduction about myself. Questions from CFD domain like turbulence modeling, wall y+, selection of turbulence model, courant number, transient simulation. How much flow time should one take for transient simulation and how to chose a time step value? Then he asked me about Pumps, working principle of centrifugal pumps, components of pumps, NPSH, pump characteristics curves. Telephonic round went for around 35 minutes
