Investigation of surface pressure response of a flat plate encountering flowinduced vortices due to a cylinder
The flow generated noise for flow bluff or streamlined bodies in the flow is an important modern engineering problem.

Prevention or reduction the noise is critical from a military perspective. Hydrodynamic noise due to turbulent flow over a lifting surface such as a propeller or hydrofoil is a flow that can be analysed theoretically and through numerical analysis methods such as computational fluid dynamics (CFD).

The approach adopted here is to combine an upstream cylinder and a downstream sharp edged flat plate.

Abstract
The flow generated noise for flow bluff or streamlined bodies in the flow is an important modern engineering problem. Noise -intended to be reduced- is encountered in all areas of our lives, such as air conditioners, refrigerator cooling fans, helicopter-drone propellers, ship propellers, aircraft wings and rotors, landing gears, and wind turbines. In oceans, noise pollution has increased in recent years. Unintended noise at sea can be an issue for both passengers, crew, and marine life. Prevention or reduction the noise is critical from a military perspective. Hydrodynamic noise due to turbulent flow over a lifting surface such as a propeller or hydrofoil is a flow that can be analysed theoretically and through numerical analysis methods such as computational fluid dynamics (CFD). However, it is hard to understand the complexity of the flow interaction between upstream turbulence and the sound propagation. The approach adopted here is to combine an upstream cylinder and a downstream sharp edged flat plate.
