University of Michigan TEST FOOTAGE SHARROW PROPELLER

To gain insight into the complex fluid flow through the Sharrow Propeller™, Sharrow Engineering funded the development of an enhanced 12-stream dye injection visualization system with high-speed 750 fps camera at the University of Michigan’s Marine Hydrodynamics Laboratory. Here is a video of the system in action! The video above clearly shows the larger volume of the captured stream of the Sharrow Propeller™ and greater downstream mixing. Note in the photo the outer orange streamline that is ingested into the Sharrow Propeller™ passes beyond the tip of the standard propeller. The standard propeller produces a concentrated tip vortex while the Sharrow Propeller™ has no tip vortex; the tip vortex is an induced loss and a source of cavitation.
