Garcia, Marcelo H. Parsons, Jeffrey D. 2015-09-25T21:05:01Z 2015-09-25T21:05:01Z 10000-01-01 1998 1998 In addition to gravity current front dynamics, another mixing behavior has been studied (sedimentary double diffusion, SDD). Laboratory experiments have been performed which explore conditions the only previous study did not. The experimental data obtained herein has been combined with the data from the earlier study. This comprehensive data set has been collapsed with the use of a newly-formulated theory based on gravity current dynamics. The theory formulated is similar to existing theory based upon thermal convection, but allowed for an easier extension to the flows at hand. Further, the complication of salinity has been added to the original problem of a warm, sediment-laden plume. It has been found that simple extensions of standard (i.e., two-component) double-diffusive convection could not adequately describe the behavior observed. Various possibilities were put forth to describe the results, with only a couple capable of describing the behavior (e.g., front-induced instability or Soret effects).
