Abstract

The analysis of density jumps is reconsidered and a new approximate model, based on an estimate that most of the turbulent energy produced by the jump is dissipated, is presented. The model suggests new upper bounds for the upstream Froude number, the entrainment and the downstream height. These bounds are shown to be consistent with earlier measurements.
