Some Comments on the Modeling of the Collapsing Wake

Abstract

The problem of scaling the phenomena of the collapse of the wake of a self-propelled body in a stratified fluid is examined. Conditions are derived such that the Froude number (based on body speed, length and Vaisala period) is equal for both model and prototype. Conditions are also obtained for the existence of buoyancy and inertial subranges in the wake turbulence. These conditions are applied to determine the smallest size model for which the phenomenon of wake growth and collapse is properly scaled from the prototype.
