Numerical Studies of Disperse Three-Phase Fluid Flows

The dynamics of a three-phase gas–liquid–liquid multiphase system is examined by direct numerical simulations. consists continuous liquid phase, buoyant gas bubbles, and smaller heavy drops that fall relative to the liquid. computational domain fully periodic, force equal weight mixture added keep it in place. governing parameters are selected so terminal Reynolds numbers bubbles moderate; while effect bubble deformability changing its surface tension, tension for sufficiently high they do not deform. One “unit cell” eight freely interacting examined. dependency slip velocities, velocity fluctuations, distribution dispersed phases on volume fraction each phase It found around single uneven depends deformability, relatively uniform this study.
