Velocity Fluctuations in a Slowly Sheared Bubble Raft

A surprising feature of flow in slowly sheared model foam (bubble raft) is a measured discontinuity in the rate of strain as a function of position such that part of the system is “flowing” and the rest is undergoing “elastic” deformations [J. Lauridsen, G. Chanan, and M. Dennin, Phys. Rev. Lett. 93, 018303 (2004)]. Detailed measurements of the distribution of nonlinear bubble rearrangements ha...

Zero crossings of velocity fluctuations in turbulent boundary layers

In this paper some results are presented on the statistical properties of zero crossings of turbulent velocity fluctuations in boundary layers over a wide range of Reynolds numbers. The earlier finding that the probability density function (pdf) of the intervals between successive zero crossings of the streamwise velocity fluctuation u can be approximated by two exponentials, ,* each with its o...
