Abstract
This work presents a method for performing three-dimensional numerical simulations of incompressible multiphase flows, with an emphasis on droplet deformation and breakup in simple shear flows. This is achieved through use of the Level Set method to track the interface between the two phases, alongside a projection method to simulate the fluid flow, with time steps performed with the Crank-Nicolson method and a finite difference scheme for spacial discretization. Some results are presented with the objective of code validation, by comparing droplet deformation and inclination angle for Stokes flow and varying Capillary number with theoretical and numerical results availiable in the literature, with good agreement. Some very preliminary breakup results are also presented. Future work is aimed at a more in-depth analysis of droplet breakup, with the possibility of simulating droplets made of magneto-rheological fluid.
