Physics of Reverse Flow on Rotors at High Advance Ratios
Nandeesh Hiremath, Dhwanil Shukla, Narayanan Komerath
When a rotor blade encounters reverse flow in edgewise flight at high advance ratio, a strong vortical structure forms on the leeside of the sharp blade edge. This has unexpected e…

Static Pressure Extraction from Velocimetry in Vortical Flow Fields
Nandeesh Hiremath, Jose C. Sanchez, Narayanan Komerath
Rapid fluctuations of static pressure away from flow boundaries in a low-speed vortical flow, are extracted using the measured velocity field. The technique departs from prior work…
