Droplet Study
Head-on collision of droplets has been simulated using the method of
molecular dynamics. Recognizing that previous molecular dynamics
simulations of this phenomenon have reported only coalescence, or
shattering outcomes, our results show that the collision can actually
result in either coalescence or bouncing of the colliding droplets. We
however observed bouncing only within a narrow band of state conditions,
and found that the ambient gas plays a significant, though not essential
role in effecting bouncing collision. For further information see the
paper "Molecular Simulation of Droplet Collision in the Presence of
Ambient Gas", Molecular Physics, 96, 81-5 (1999).
