In case of inviscid flow over a flat plate
WebApr 12, 2006 · Unsteady separated flow behind an inclined flat plate is numerically studied through the use of the discrete-vortex approximation, in which the shear layers emanating … WebMar 3, 2024 · The flow is everywhere turbulent and a boundary layer develops over the surface of the flat plate. The lack of separation or other more complex flow phenomena allows turbulence models to predict the flow with a high level of accuracy. Due to the choice of a low Mach number of 0.2 for this case, compressibility effects are essentially negligible.

Web3.1.1 Wave-reduction effect. In this section we demonstrate the wave-reduction effect of 2-D biplanes. We compare the wave drag of two different airfoils, a single flat-plate airfoil and a parallel flat-plate biplane, at a supersonic flow condition. The conditions are such that both airfoils generate the same amount of lift (the “constant ... WebDec 1, 2003 · The first governs the rate at which circulation is shed from the plate's edges and the second ensures that the free vortex sheets are shed tangentially. In fact, all the familiar flow characteristics associated with the imposition of the steady Kutta condition are rigorously shown to have exact parallels in the unsteady case.
