On the Nature of Turbulence in a Stratified Fluid. Part I: The Energetics of Mixing
- G. Ivey, J. Imberger
- Physics
- 1 May 1991
Abstract The definition of the flux Richardson number Rf is generalized to be the ratio of the turbulent buoyancy flux b to the net turbulent mechanical energy m available from all sources. For… Expand
The degeneration of large-scale interfacial gravity waves in lakes
- D. Horn, J. Imberger, G. Ivey
- Geology
- 1 May 2001
Mechanisms for the degeneration of large-scale interfacial gravity waves are identified for lakes in which the effects of the Earth's rotation can be neglected. By assuming a simple two-layer model… Expand
Modeling basin‐scale internal waves in a stratified lake
- B. Hodges, J. Imberger, A. Saggio, K. Winters
- Geology
- 1 November 2000
Basin-scale internal waves provide the driving forces for vertical and horizontal fluxes in a stratified lake below the wind-mixed layer. Thus, correct modeling of lake mixing and transport requires… Expand
Unsteady natural convection in a rectangular cavity
- J. Patterson, J. Imberger
- Geology
- 11 September 1980
The problem of transient natural convection in a cavity of aspect ratio A [les ] 1 with differentially heated end walls is considered. Scale analysis is used to show that a number of initial flow… Expand
Structure of bubble plumes in linearly stratified environments
- T. Asaeda, J. Imberger
- Physics
- 1 April 1993
Bubble plumes in a linearly stratified ambient fluid are studied. Four well-defined flow regions were observed: an upward-moving bubble core, an inner plume consisting of a mixture of bubbles and… Expand
The degeneration of internal waves in lakes with sloping topography
- L. Boegman, G. Ivey, J. Imberger
- Geology
- 1 September 2005
In a laboratory study, we quantified the temporal energy flux associated with the degeneration of basin-scale internal waves in closed basins. The system is two-layer stratified and subjected to a… Expand
On the nature of turbulence in a stratified fluid
- G. Ivey, J. Imberger
- Environmental Science, Physics
- 1 May 1991
Abstract A strong debate has continued for a number of years over the magnitude of the ratio of the buoyancy flux b to the rate of production of turbulent kinetic energy from the mean velocity sheer.… Expand
Convective motions in the sidearm of a small reservoir
- S. Monismith, J. Imberger, Michael L. Morison
- Environmental Science
- 1 December 1990
We present observations of the diurnal formation of horizontal temperature gradients in the surface waters of a sidearm of a small water supply reservoir at a time during summer when radiative… Expand
One- and three-dimensional biogeochemical simulations of two differing reservoirs
- J. R. Romero, J. Antenucci, J. Imberger
- Environmental Science
- 1 May 2004
Abstract A one-dimensional hydrodynamic model was coupled to an aquatic ecological model and applied to two differing reservoirs with one set of parameters. Simulations over 2 years of small (area=5… Expand
