Dependence of Mixed-Layer Entrainment on Shear Stress and Velocity Jump.

Abstract

From new rotating-screen annulus experiments, the mixed-layer growth rate is found to depend on both the surface friction velocity and the interfacial velocity jump in a multiplicative sense, with the velocity-jump dependence being the stronger. The dimensionless velocity-jump parameter, Rv, can vary substantially during entrainment. The effect of sidewall friction, if not too strong, is to decrease the entrainment rate through its increase of Rv. (Author)
