Flow oscillation
Consider an infinitely long plate which is oscillating with a velocity in the direction, which is located at in an infinite domain of fluid, where is the frequency of the oscillations. The incompressible Navier-Stokes equations reduce to where is the kinematic viscosity. The pressure gradient does not enter into the problem. The initial, no-slip condition on the wall is WebOscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. ... This transfer typically occurs where systems …
