Résumé

This paper presents numerical solutions for the flowfield transients with a single jet of cold liquid entering horizontally at the bottom of a tall tank initially filled with hotter liquid which is removed at the top of the tank. Early in the filling process, the inflow of the higher density liquid produces a gravity current which propagates across the tank floor. When turned by the wall opposite the jet, the gravity current generates a range of internal wave phenomena which are apparent in oscillations of the thermocline. The region below the thermocline is initially filled with a complex pattern of recirculaiton cells, which evolves to a pattern dominated by the jet vortex as the thermocline moves away from the inlet.
