INVESTIGATION OF NEWTONIAN AND NON-NEWTONIAN DROPLETS IN COLLISION WITH THE HEATED ULTRAPHOBIC SURFACE ON VARIOUS WEBER NUMBERS
Super
hydrophobic surfaces due to water repelling property, have a considerable
potential for the use in various modern technologies. In this paper, the
collision between Newtonian
and non-Newtonian droplets with a super-hydrophobic hot surface like graphite
has been simulated. The contact angle is 140 and 160 degree. Simulation yielded
proper result compared to the experimental results. It is found that the temperature
effect on hydrophobic surfaces is negligible. Our results demonstrate that the
dimensionless drop diameter increases with the Weber number. It is revealed
that a Newtonian droplets shows different behavior compared to a non-Newtonian
one especially at higher temperatures.
