Sentence examples for sound scattering from inspiring English sources

Examples are shown to illustrate the thermal and viscous effects on sound scattering.

Both solutions are applied to two known problems of sound scattering and radiation by a rigid sphere in variable pressure and velocity fields.

The aim of this work is to predict sound pressure in front of wall facings based on periodic sound scattering surface profiles.

A direct assessment of this algorithm coupled with an interior 2 4 Mac Cormack scheme for sound scattering computations based on the 2D inviscid gas dynamics equations is performed using comparison with theoretical scattering results.

Additionally, the wall shear stress originating from the interaction between the turbulent flow and the pervious wall affects the sound propagation in the lined duct and the sound scattering at the discontinuities of the wall compliance.

The study aims at evaluating the ability of an alternative time-domain approach, the Transmission Line Matrix (TLM) method, to model sound scattering by cylindrical scatterers.

If these concerns sound scattered, it is because Beck's followers feel beset from many sides — political, racial, religious.

The low Mach number vortex sound scattered by a sharp wedge formed by a rigid and an acoustically softer material is analyzed theoretically in the present investigation.

By using high-order finite-difference schemes to discretize compressible Navier Stokes equations, the sound scattered on airfoil surface is directly resolved as an unsteady pressure fluctuation.

We show that the axisymmetric mode of the source is the most acoustically efficient, similarly to what is seen for free jets; but unlike the latter problem, the sound scattered by the trailing edge is only weakly dependent on the details of the wavepacket envelope and on the two-point coherence of the source, the wavepacket phase speed being the salient feature for installed jet noise.
