Within a narrow band of flight conditions in the transonic regime, interactions between shock-
waves and intermittently separated shear layers result in large amplitude, self-sustained …

Combustion noise is becoming increasingly important as a major noise source in
aeroengines and ground based gas turbines. This is partially because advances in design …

The application of a low-cost computational aeroacoustics (CAA) approach to a slat noise
problem is studied. A fast and efficient stochastic method is introduced to model the …

Noise generated by civil transport aircraft during take-off and approach-to-land phases of
operation is an environmental problem. The aircraft noise problem is firstly reviewed in this …

, the sound wave propagation in the flow field outside the separation of a transonic buffet
flow at a Mach number M∞= 0.73 and an angle of attack α= 3.5 over a DRA 2303 …

This study utilizes a hybrid aeroacoustic model to investigate how airfoils with spanwise
wavy geometries can be used to reduce trailing-edge noise alongside improving the …

The current status of a computational aeroacoustics (CAA) approach to simulate broadband
noise is reviewed. The method rests on the use of steady Reynolds averaged Navier–Stokes …

A computational methodology is proposed for aerodynamic noise prediction of long-span
bodies at low Mach numbers. The three-dimensional hydrodynamic field is computed by …

In this contribution, a hybrid zonal simulation tool with volumetric inflow turbulence forcing is
applied to trailing-edge noise of a NACA0012 airfoil with and without a porous insert at …

This manuscript reports on the effects of application of porous material on the trailing edge of
a 3D cambered airfoil. The numerical study has been carried out following a zonal Overset …
