When the pressure fluctuations caused by turbulence vorticity in the boundary layer are
scattered by a sharp trailing edge, acoustic energy is generated and propagated to the far …

The present review covers the latest evolution of computational aeroacoustics, the field that
deals with the noise generated by fluid flows and its propagation in the medium. It highlights …

This contribution benchmarks the aeroacoustic workflow of the perturbed convective wave
equation and the Ffowcs Williams and Hawkings analogy in Farassat's 1A version for a low …

The present work deals with the modeling of the aerodynamic sound generated by the
propellers of small-size drones, taking into account the effects of horizontal forward flight …

A detailed experimental study on the aerodynamic performance and noise emission of
airfoils and fan blades with permeable leading edges under disturbed inflow conditions was …

A wall-modeled statistically converged Large Eddy Simulation (LES) of the turbulent flow in
the NASA Source Diagnostic Test turbofan has been successfully performed for the first time …

Axial fans are widely used in the aerospace field, and new regulations and environmental
concerns are prompting manufacturers to design efficient low-noise axial fans. The …

Purpose The purpose of the paper is to predict the aerodynamic performance of a complete
scale model H-Darrieus vertical axis wind turbine (VAWT) with end plates at different …

Noise from axial fans typically increases significantly as the tip clearance is increased. In
addition to the broadband tip clearance noise at the design flow rate, narrowband humps …

Axial fans represent a major source of noise in technical systems. Based on investigations
on airfoils, a promising measure for reducing the sound emission of such systems with axial …
