Entraining Flow of a Concentrated Benthic Suspension: Computations with the Prandtl Mixing-Length Model

The Prandtl mixing-length model of turbulent exchange of mass and momentum is applied to calculate the entrainment of overlying water into a layer of suspended fine sediment at a horizontal bed. In the field the flow and turbulence in such a concentrated benthic suspension (CBS) are driven by a streamwise pressure gradient resulting from the...

Turbulent mixing layers in shallow water

This investigation on shallow mixing layers has two main objectives: - To gain insight in the influence of the depth on the evolution of large, horizontal eddies in a lateral mixing layer in a shallow free-surface flow. - To gain insight in the contribution of these eddies to the entrainment into the layer and to the mixing and to the transport...

A model for the calculation of the properties of a jet in a three dimensional non-uniform main flow

A model is derived for the calculation of the properties of a jet exhausting into a non-uniform main flow, at an arbitrary angle to the initial jet direction. The model is a generalisation of an earlier jet-ina-main flow model for uniform main flows. Semi empirical input is limited to an entrainment relation and a relation for form factors of...
