This is Dr. P.K.Maji 's work, who was a Ph.D. student in Computational Fluid Dynamics Dept. of Mechanical Engg. in IIT Kanpur. He had simulated fluid flow on a body fitted structured grid of a hydraulic turbine for dirrerent Reynold's no.
Graphics simulation was done by me using Post Processor graphics.
