Numerical investigation of tip clearance effects on the performance of ducted propeller
International Journal of Naval Architecture and Ocean Engineering, 2015 Tip clearance loss is a limitation of the improvement of turbomachine performance. Previous studies show the Tip clearance loss is generated by the leakage flow through the tip clearance, and is roughly linearly proportional to the gap size.
