- •
Combination of Marangoni and buoyant forces generate circulation cells in droplet.
- •
Nusselt number increases with increasing contact angle due to combined effects of advection and diffusion.
- •
Nusselt number increase becomes substantial for further increase in contact angle.
- •
Bond number increases with increasing contact angle.
