Trailing-edge noise is the dominant contributor to the noise generated by aircraft and wind
turbines. Serrations on the trailing edge play a crucial role in suppressing the aerodynamic …

This paper presents an experimental study on the aeroacoustics of a flat plate rig with a
highly instrumented serrated trailing-edge. The role of near-field flow properties, namely …

The silent flight achieved by owls is attributed to their unique wing morphologies,
characterized by leading-edge (LE) serrations, trailing-edge (TE) fringes, and a velvet-like …

Inspired by the owl's silent flight, we experimentally investigated the flow control mechanism
of the soft trailing fringes (STFs) on the wake of the S833 airfoil at the Reynolds number of …

Aiming at reducing the blunt trailing edge noise of flat plate, three-dimensional structured
porous media with uniform and non-uniform porosities are designed. Acoustics and flow …

A significant extension of previously introduced continuous eddy simulation methods is
presented by introducing minimal error partially and fully resolving simulation methods for …

A dynamic version of the improved delayed detached-eddy simulation (IDDES) based on the
differential Reynolds-stress model (RSM), referred to as the RSM-DynIDDES, is developed …

In this paper, an approach for the reduction of trailing edge noise due to flow scattering from
a semi-infinite splitter plate is proposed. It utilizes the fluid–structure interactions of well …

In the present work, the force term is first derived in the spectral multiple-relaxation-time high-
order lattice Boltzmann model. The force term in the Boltzmann equation is expanded in the …

A novel concept of utilizing distributed surface compliance to achieve airfoil tonal noise
reduction at various loading conditions is proposed. The aeroacoustics of airfoil …
