A numerical investigation is conducted on aerodynamic noise of flow past a circular cylinder
with different spanwise lengths (0.5πD, πD, 2πD, and 4πD) at Re= 10 000, where D is the …

In this study, we introduce a novel arrangement consisting of two arc plates around a
cylinder with the privilege of improved fluid flow and noise control. The arc plates are placed …

This study experimentally investigates the potential of using surface pattern fabrics for the
cylinder noise and drag control in different Reynolds number ranges. The aerodynamic and …

Through anechoic wind tunnel tests, this study comprehensively investigates the noise and
drag reductions on a circular cylinder with dimples. Dimples built on a surface pattern fabric …

The compressible flows past a wavy-axis square cylinder are numerically carried out by
means of the large-eddy simulation technique for two different free-stream Mach numbers (⁠ …

The noise mitigation effect of bio-inspired geometries has attracted growing attention from
both research and industry, such as the vibrissa-shaped cylinder derived from the harbor …

Efficient prediction and evaluation of noise performance are crucial to the design and the
optimization of landing gear noise. A systematic method is developed to predict and …

A hybrid method incorporating the simulations of noise sources with delayed detached eddy
simulation (DDES) and calculations of far-field noise with the Ffowcs Williams–Hawkings …

In this short paper, we derive the on-wall values and the wall-normal derivatives of the
Laplacians of pressure and kinetic energy density at the wall for incompressible viscous flow …

The noise of landing gears is a major contributor to the overall airframe noise of an aircraft
during approach and landing. In this paper, a novel strut treatment method, termed the …
