The entrainment and mixing processes in an axisymmetric vertical turbulent buoyant jet and its transition from a jet to a plume have been studied. The ambient fluid is of uniform density and calm except for the flow induced by the jet, and the...

Theoretical and experimental studies were made on two classes of buoyant jet problems, namely:
1) an inclined, round buoyant jet in a stagnant environment with linear density-stratification;
2) a round buoyant jet in a uniform cross stream of...

This study considers the run-up of non-breaking and breaking solitary waves on a smooth sloping beach. A non-linear theory and a numerical model solving the non-linear shallow water equations (NLSW) were developed to model this physical process....

The exchange of nonlinearly adsorbing compounds between stream water and sediment beds covered with stationary bedforms was investigated in laboratory experiments. The dominant physical exchange process is advective pumping caused by dynamic...

Theoretical solutions were obtained for four classes of turbulent buoyant jet problems, namely,
1) an inclined, round buoyant jet in a stagnant, uniform ambient fluid;
2) an inclined, round buoyant jet in a stagnant ambient fluid with linear...

The objective of this investigation is to examine the buoyancy-driven gravitational spreading currents, especially as applied to ocean disposal of wastewater and the accidental release of hazardous fluids, such as liquefied natural gas.
A series...

The interaction of normally incident time-periodic water waves with a density-stratified fluid in a rectangular trench is studied experimentally and theoretically; the fluid outside the trench is homogeneous.
This investigation has focused on...
