Abstract
Noise generated by the flow around bluff or streamlined bodies is still a significant engineering challenge. This unintended noise issue arises in numerous applications, including air conditioners, refrigerator cooling fans, helicopter-drone propellers, ship propellers, aircraft wings and rotors, landing gears, and wind turbines. Additionally, the rising concern over ocean noise pollution has emphasized the need to address this problem to protect passengers, crew, and marine life, with particular significance from a military viewpoint. Analysing hydrodynamic noise caused by turbulent flow over lifting surfaces can be tackled through theoretical approaches and numerical methods, such as computational fluid dynamics. However, comprehending the chaotic interaction between upstream turbulence and sound propagation remains a complex task, requiring innovative solutions. Managing noise generated by flow around different bodies is a multifaceted challenge with wide-ranging implications across various industries. As advances are made in understanding noise generation and propagation, the pursuit of effective noise reduction methods becomes increasingly critical.
