We present measurements of the density and velocity elds produced when an oscillating circular cylinder excites internal gravity waves in a strati ed uid. These measurements are obtained using aâ€¦ (More)

The results of an experimental study of the non-Boussinesq lock-exchange problem are described. The experiments were performed in a rectangular channel using water and either a sodium iodide solutionâ€¦ (More)

Self-similar plane solutions for the inertial stage of gravity currents are related to the initial parameters and a coefficient that is determined by the boundary condition at the front. Differentâ€¦ (More)

This paper examines intrusive Boussinesq gravity currents, propagating into a continuously stratified fluid. We develop a model, based on energy arguments, to predict the front speed of such anâ€¦ (More)

The coalescence of two co-flowing axisymmetric turbulent plumes and the resulting single plume flow is modelled and compared to experiments. The point of coalescence is defined as the location atâ€¦ (More)

Two-dimensional variable-density Navierâ€“Stokes simulations have been conducted in order to investigate the effects of a slope on the classical lock-exchange flow. Simulations of full lock releasesâ€¦ (More)

We perform laboratory experiments in a recirculating shear ow tank of non-uniform salt strati ed water to examine the excitation of internal gravity waves in the wake of a tall, thin verticalâ€¦ (More)

We describe new experiments to measure the penetrative entrainment by a turbulent fountain in a steady two-layer stratification. A theoretical model was established by assuming that theâ€¦ (More)
