Merging of spreading drops - computational results 

Simulations of thin liquid films and drops in higher dimensions, with J. Diez, J. Comp. Phys. 173, 274 (2002)

Animation of the merging process: 2D or 3D .

Zoom of the coalescence region: 2D .

Before and after the merge:

(note that symmetry allows for simulating only 1/4 of the domain)

Coalescence region:

(note formation of a satelite droplet)
