This article reviews the development and application of Computational AeroAcoustics (CAA)
to acoustic propagation on subsonic mean flows, with a particular focus on methods used to …

A spanwise-periodic computation of a turbulent flow past a Gaussian bump is performed in
the form of a hybrid direct numerical simulation and wall-resolved large-eddy simulation. A …

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 …

Conventional explicit finite-difference methods have difficulties in handling high-frequency
components due to strong numerical dispersions. One can reduce the numerical dispersions …

This paper reports the results from a direct numerical simulation of an initially turbulent
boundary layer passing over a wall-mounted “speed bump” geometry. The speed bump …

A set of optimised boundary closure schemes is presented for use with compact central finite
difference schemes in computational aeroacoustics (CAA) involving non-trivial boundaries …

In this paper simple polynomial interpolation is used to derive arbitrarily high-order compact
schemes for the first derivative and tridiagonal compact schemes for the second derivative …

JET noise reduction is one of the major issues concerning jet engine manufacturers.
Environmental concerns and strict noise regulations around major airports have made jet …

We present a Fourier continuation (FC) algorithm for the solution of the fully nonlinear
compressible Navier–Stokes equations in general spatial domains. The new scheme is …

Wall-resolved implicit large-eddy simulations based on spatial filtering are performed for
shock-induced flow separation over an axisymmetric bump at a Mach number of 0.875 and a …
