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...
متن کاملA 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...
متن کاملFlow around a NACA0018 airfoil with a cavity and its dynamical response to acoustic forcing
Trapping of vortices in a cavity has been explored in recent years as a drag reduction measure for thick airfoils. If, however, trapping fails, then oscillation of the cavity flow may couple with elastic vibration modes of the airfoil. To examine this scenario, the effect of small amplitude vertical motion on the oscillation of the shear layer above the cavity is studied by acoustic forcing sim...
متن کاملusing adaptive meshing for solving the transonic flow around airfoils
numerical analyses have shown that successful flow simulations and the accuracy of solution noticeably depend on the number of nodes used in computational meshing. a suitable meshing should have the capability of adapting with main flow parameters. because the number of total nodes that can be used in numerical simulation is limited, making such grid for complex flows is almost difficult, if it...
متن کاملAerodynamic Noise Computation of the Flow Field around NACA 0012 Airfoil Using Large Eddy Simulation and Acoustic Analogy
The current study presents the results of the aerodynamic noise prediction of the flow field around a NACA 0012 airfoil at a chord-based Reynolds number of 100,000 and at 8.4 degree angle of attack. An incompressible Large Eddy Simulation (LES) turbulence model is applied to obtain the instantaneous turbulent flow field. The noise prediction is performed by the Ffowcs Williams and Hawkings (FW-...
