Abstract

The phenomena of binary droplet collision is seen in dispersed phase systems such as sprays in internal combustion engines, gas turbines, etc. The present work aims at understanding off-center collision dynamics of two droplets of unequal sizes. High fidelity simulations are performed using three dimensional, two phase- finite volume based solver in OpenFOAM platform. Volume of fluid (VOF) method is used for interface capturing. Navier-Stokes equations are solved using a projection algorithm. Simulations are done with MPI parallelization to meet the computational demand. The solver is validated against droplet splashing benchmark test case. The present numerical results study the effect of impact parameter and diameter ratio on droplet collision dynamics.
