Abstract:
|
In this study, numerical simulations of binary droplet collisions of two GNF droplets are carried out. Navier-Stokes equations are solved for fluid motion both inside and outside of the droplet using a conservative level-set/finite-volume approach. On headon collision of equal-sized droplets, implementation of symmetry boundary condition along with ghost nodes are used to mimic the behavior of the droplet colliding an image of itself while only one-eight of the domain being solved. A novel lamella stabilization approach is used which enables us to simulate extreme collision cases in relatively coarse meshes. The results are compared with available experimental and numerical results. |
