The numerical prediction of droplet deformation and break‐up using the Godunov marker‐particle projection scheme

The problem of droplet deformation and break‐up is considered. A hybrid Eulerian–Lagrangian method is used in which the velocity and pressure are discretized on a fixed mesh and Lagrangian particles are used to implicitly track the interface between the two phases. The Navier–Stokes equations are solved using an approximate Godunov projection method, collectively called the Godunov marker‐particle projection scheme. The results show good qualitative agreement with previous research as well as demonstrating the efficacy of the method. Copyright © 2007 John Wiley & Sons, Ltd.
