Active/Adaptive Morphing Propellers for Enhancing Critical Cavitation Speed and Performance
The thesis focuses on the development and analysis of a morphing system for a boat propeller, aiming to increase the critical cavitation speed. Cavitation, a phenomenon that can impair the performance and durability of propellers, occurs when local pressure drops below the vapor pressure, leading to the formation of vapor bubbles that collapse, causing noise…
