Whistling of an orifice in a reverberating duct at low Mach number

The Journal of the Acoustical Society of America, 2011
An experimental investigation of the parameters controlling the whistling frequency and amplitude of an orifice in a confined turbulent flow is undertaken. A circular single hole orifice with sharp edges, a hole diameter equal to 0.015 m and a thickness equal to 0.005 m, is arranged in an air test rig with an inner diameter equal to 0.03 m.

Low Mach Number Flows in Time-Dependent Domains

SIAM Journal on Applied Mathematics, 2003
This paper concerns with a multiscale asymptotic analysis of a barotropic fluid motion in a bounded time-dependent domain when the time derivation of a boundary is small compared to the acoustic velocity of the fluid. The author introduces two scales for the time variable and one scale for the space variable.

A high‐resolution scheme for low Mach number flows

International Journal for Numerical Methods in Fluids, 2004
AbstractA method for computing low Mach number flows using high‐resolution interpolation and difference formulas, within the framework of the Marker and Cell (MAC) scheme, is presented. This increases the range of wavenumbers that are properly resolved on a given grid so that a sufficiently accurate solution can be obtained without extensive grid ...

Simulation of low Mach number fluids

2010
In dieser Arbeit werden die Navier-Stokes Gleichungen für kompressible Fluide mittels eines von N. Kwatra et al. vorgeschlagenen Verfahren gelöst. Dieses Verfahren filtert effektiv Schallwellen, wodurch eine signifikant größere zeitliche Schrittweite erreicht werden kann als bei herkömmlichen Verfahren. Dies wird an Simulationen von stellare Konvektion
