Integrating a porous material into the structure of an aerofoil constitutes a promising passive
strategy for mitigating the noise from turbulence–body interactions that has been extensively …

This paper is a predominantly experimental study into the use of porosity located
downstream of an aerofoil leading edge for the reduction of turbulence interaction noise …

Airfoil turbulence interaction noise and the flow field up to and over the porous leading edge
is experimentally studied. The porous leading edges were of the same base triply periodic …

In a large number of applications, heat exchanger modules consist of a combination of a
heat exchanger and a turbomachinery. An axial fan is often used as the turbomachine in …

One of the major aerodynamic noise generation mechanisms is the interaction of a turbulent
flow with a downstream blunt object, such as the blade of a rotating fan or a fixed stator. A …

A novel active turbulence grid of the Institute of Fluid Mechanics at FAU Erlangen-
Nuremberg is introduced. The focus of this grid is not on basic investigations of fluid …

An experimental campaign was undertaken to assess the performance of axial fan blades
under various conditions, including unskewed, forward-skewed, and backward-skewed fan …

fundamental investigation of the noise radiated by two flat plates in a tandem configuration …

Engineers' work is often linked with the development and production of technical products. In
order to improve products and processes, digitalization is more and more applied to each …

The design process of axial fans is based on increasing the aerodynamic efficiency and
reducing the sound emissions. Low noise emissions are regarded as a quality feature and …
