Spatial Distribution of Resonance in the Velocity Field for Transonic Flow over a Rectangular Cavity

Numerical Simulations of Transonic Flow Acoustic Resonance in Cavity

Direct numerical simulations are used to investigate transonic flow acoustic resonance in an open cavity. The numerical scheme minimizes the errors due to dispersion and dissipation of acoustic waves, and resolves both the unsteady flow and radiated acoustic field. Implicit solution of the compressible Navier-Stokes equations is obtained using a compact high-order spacial differencing scheme, c...

A Flow-resonant Model of Transonic Laminar Open Cavity Instability

A transonic air stream flowing over a rectangular cavity or enclosure is unsteady. At certain flow conditions, large scale oscillations develop in the shear layer which, for an open cavity, spans across the whole enclosure. The convected shear layer instabilities interact with the cavity geometry, they generate resonance, and induce large amplitude wall pressure fluctuations, aerodynamic pressu...
