liquid droplet on a solid surfa</span><span style=\"font-family:Verdana;\">ce with tem</span><span style=\"font-family:Verdana;\">perature gradient. Both fluid mechanics and heat trans</span><span style=\"font-family:Verdana;\">fer are
incorporated in the model. The Navier-Stokes equation is employed both inside
and outside the droplet. Size variation is observed in the transient
simulation. Results show that the velocity of the migration is about 1.7 mm/s
under a temperature gradient of 30 K/mm. The model is consistent with results with
previous literatures.
