摘要

In this pap</span><span style="font-family:Verdana;">er, we established a time-dependent model that inv</span><span style="font-family:Verdana;">estigate</span></span><span style="font-family:Verdana;">s</span><span style="font-family:""><span style="font-family:Verdana;"> the migrati</span><span style="font-family:Verdana;">on behavior of a millimeter-scale 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.
