Two-Phase Nonturbulent Flow with Applications

Figure 3

Dynamics of the density distribution of the pollutant moving upwards with the sink moving together with the pollutant (optimal speed). We have stopped the sink after iterations. We extracted around 85 percent of the pollutant before the sink is stopped. Here, red, yellow, green, and blue color denote densities 0.35, 0.46, 0.52, and 0.6, respectively. (a) At the initial moment, the pollutant is undisturbed at the bottom. (b), (c) After and iterations pollutant is rising while we are extracting it at point moving by the law . (d) At , we see further evolution of pollutant.
