Fluid-Structure Interaction Analysis of Hydrofoils in a Pulsating Flow

Fluid-Structure Interaction Analysis of Hydrofoils in a Pulsating Flow

The reduction of noise and vibration are very important in the design of hydrofoils. The current study focuses on establishing a theoretical and numerical model to investigate fluid-structure interaction caused by elastic hydrofoils in a pulsating flow. A fully coupled three dimensional boundary ele...
