High Reynolds number oscillating contact lines
For the eventual use as regards wave generation and damping, we investigate oscillating contact lines on vertical walls. Stainless steel is used rather than the glass of Ting and Perlin [J. Fluid Mech. 295 (1995) 263] for the vertically sinusoidally oscillating plate over a large range of Reynolds numbers. The non-wetting stainless steel minimizes the static meniscus ignored in our analysis. Ot...
متن کاملHigh–Reynolds Number Wall Turbulence
We review wall-bounded turbulent flows, particularly high–Reynolds number, zero–pressure gradient boundary layers, and fully developed pipe and channel flows. It is apparent that the approach to an asymptotically high– Reynolds number state is slow, but at a sufficiently high Reynolds number the log law remains a fundamental part of the mean flow description. With regard to the coherent motions...
متن کاملLinear drag law for high-Reynolds-number flow past an oscillating body
the problem in order to investigate the fluid mechanical consequences of combined dc and ac motions. Specifically, we will vary the relative magnitudes of the (time-averaged) ac speed w and the dc speed U in order to explore a range of fluid dynamic conditions, from purely steady to strongly unsteady. For dc-dominated conditions, one expects that local flows generated in one oscillation are lef...
متن کاملBurgers’ equation with high Reynolds number
Burgers’ equation, involving very high Reynolds numbers, is numerically solved by using a new approach based on the distributed approximating functional for representing spatial derivatives of the velocity field. For moderately large Reynolds numbers, this simple approach can provide very high accuracy while using a small number of grid points. In the case where the Reynolds number >10, the exa...
متن کاملOlfactory search at high Reynolds number
Locating the source of odor in a turbulent environment-a common behavior for living organisms-is nontrivial because of the random nature of mixing. Here we analyze the statistical physics aspects of the problem and propose an efficient strategy for olfactory search that can work in turbulent plumes. The algorithm combines the maximum likelihood inference of the source position with an active se...
