... of the vortex dipoles induced by the jet momentum in a stratified fluid is validated against the previous experimental study. The wakefield caused by a propeller in a linearly stratified ambient is studied and compared to the jet flow case. INTRODUCTION The flow in a density-stratified ambient is of great...

... jet trajectory numerical investigation buoyancy jet stratified fluid center line water surface ABSTRACT In general, the thermal jet flow generated by cooling water discharge from submarine is modeled as the horizontal thermal buoyancy jet. Most of the previous experimental researches do...

... ABSTRACT Internal waves in the oceans play critical roles in the large scale transport processes, and will interact with surface waves in producing complex wave patterns and dynamics. Triad resonance can occur among three components of internal waves in stratified fluids when the angular...

.../D = 7, 8, 9, 10, 11 have been chosen, and the major axis ( L ) is aligned with the incoming flow. The Reynolds number based on the minor axis ( D ) and the incoming velocity ( U ) is Re = 10 6 . All the simulations are placed in the linearly stratified fluid background with a constant buoyancy...

... ABSTRACT The motion and turbulent wake characteristics of underwater vehicles in stratified fluid is of great importance and not yet fully understood. In this work, a methodology is proposed to predict density stratified flows and wakes past a sphere. The density difference is set based...

... ABSTRACT The vortex shedding was simulated by viscous CFD technique when the linearly stratified fluid past a hydrofoil at a constant speed. Based on thermal density current model, the linear stratification of density was achieved by specifying the distribution of temperature. The RANS method...

... on the simulation of discharges of produced water in the marine environment were conducted by using jet discharging into the stratified fluid with the cross flow. In the experimental works of Koh et al. (1973), Wright (1977), and Hwang and Chang (1986), they all used the camera to take pictures of dye observation...

...-Stratified Fluid Athanassios A. Dimas and George S. Triantafyllou The City College of CUNY New York. USA ABSTRACT The two-dimensional interaction of a shear flow with a free sur- face in a stratified fluid is studied numerically, and the results are compared to the behavior of the same flow...
