摘要
The bubble plume is considered a transport phenomenon capable of generating large-scale convection due to the buoyancy of bubbles. The surface flow generated by a bubble plume is a technique proposed to collect surface-floating substances, especially in the case of an oil layer formed during large oil spill accidents to protect naval systems, rivers, and lakes. The motivation of this research is to broaden the understanding of oil flow in the stratified layer of oil on the free surface. In this case, the difference in density and viscosity between the two fluids causes an unsteady interface motion. The numerical simulation based on the Eulerian-Lagrangian model has been carried out to investigate the multidimensional motion of water and oil due to bubbles. The results of this investigation correspond well with the experimental results that were obtained in our earlier paper. © 2019 by Begell House, Inc. www.begellhouse.com
