Pressure Distribution in Confined Jet Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A momentum jet injected into a confined container breaks up to “diffusive turbulence†after traveling a critical distance. It has been argued that an adverse pressure gradient developing within the container, acting ...
Effects of Background Rotation on Turbulent Line Plumes
Publisher: American Meteorological Society
Abstract: Polar ice cap cracks open sporadically to form thin, long, narrow channels of open water, which are referred to as ?leads.? When the open water is exposed to ambient air in the winter, surface freezing occurs, thus rejecting ...
A Numerical Model of the Fluid Motion at a Density Front in the Presence of Background Turbulence
Publisher: American Meteorological Society
Abstract: The effects of background turbulence on gravity currents produced by lock exchange are investigated using a numerical model with the aim of understanding the fluid motions associated with coastal fronts. It is shown that, ...
Vertical Mixing and Transports through a Stratified Shear Layer
Publisher: American Meteorological Society
Abstract: A stratified shear layer was generated in the laboratory by driving a turbulent mixed layer of depth D over a quiescent, deep dense layer. As a result, a density interface of thickness δb across which the buoyancy jump is ...
Mixing on a Shallow Shelf of the Black Sea
Publisher: American Meteorological Society
Abstract: Microstructure measurements were carried out on the shallow shelf of the Black Sea, from the sea surface to the bottom, using a free-falling BAKLAN-S profiler released from an anchored ship. A northeast to southwest transect ...
Flows Induced by the Impingement of a Two-Dimensional Thermal on a Density Interface
Publisher: American Meteorological Society
Abstract: Laboratory experiments were carried out to investigate the fluid motions resulting from the impingement of a descending thermal on a sharp density interface with the hope of gaining insight into lead-induced convection in ...
In Situ Calibration of Hot-Film Probes Using a Collocated Sonic Anemometer: Implementation of a Neural Network
Publisher: American Meteorological Society
Abstract: Although the integral quantities of atmospheric turbulence are conveniently measured using sonic anemometers, obtaining relevant finescale variables such as the kinetic energy dissipation using conventional hot-film/wire ...
On the Rate of Frazil Ice Formation in Polar Regions in the Presence of Turbulence
Publisher: American Meteorological Society
Abstract: The purpose of this paper is to present the results of a series of laboratory experiments aimed at understanding the frazil ice growth in polar regions during the summer whence a freshwater layer at temperature 0°C spreads ...
