Multiphase modeling of droplet fall using euler-Euler approach

Abstract

This work pertains to dynamic’s modeling of multiphase flows using two models of the Euler-Euler approach: VOF and Eulerian model. Different phases were treated as interpenetrating domains, and the theory of volume fraction was introduced. The mathematical model of multiphase flow consists of Navies-Stokes (NS) differential equations. The finite volume method was used for the numerical calculations. The droplet falling process was presented to show the differences in analyzed models. Numerical tests included flow analysis of the following phases: air, gasoil and water. Numerical results were presented as contours and time-function trend of volume fraction phases.
