Abstract:To extend the knowledge gained to this point to the field observations, we found that the plunging flows in the field could be different from those in current theoretical and laboratory scale modeling. In particular, two unusual and speculated observations drew our attention: Fleenor and Schladow (2000) reported an exceptionally high initial mixing coefficient and Best et al. (2005) observed a shifting plunge line and pulsing underflows in the field. In this research, we developed a theoretical model, an interplay between the flow momentum upstream of the plunge line and the turbulent Rayleigh-Taylor instability, to offer rational explanations for these two special observations.
