Abstract

Density current is one of the natural phenomena, which plays an important role in the emission of pollution. Therefore, understanding the behavior of this phenomenon is important for the prediction and control of such emission. In this paper, the spread of three-dimensional, turbulent and unsteady inclined TURBIDITY CURRENTs has been investigated. The experimental results were normalized in the form of non-dimensional plots and then a theoretical model was presented. The current width b vs distance x from the source was normalized with respect to the initial buoyancy length scale, and the related time was normalized with respect to the initial buoyancy time scale. The results show that in the plots of non-dimensional current width vs non-dimensional distance and non-dimensional time, two regimes R1 and R2 are distinguished. This indicates that in these two regimes, the amount and type of the balanced forces are different. In regime R1, the rate of lateral growth is less than that in regime R2, while the current width in R1 and R2 regimes are proportional to and, respectively.
