Abstract
The interaction of a liquid drop with a copper surface is studied. The substrate is assumed
to be superhydrophobic with a wetting angle of
\( 150^\circ \). Based on the volume of the drop, the Bond and Weber numbers are
approximately 0.23 and 1.6, respectively. The temperature of the surface and the surrounding air
is 298 K, and the temperature of the liquid drop is 5K lower. Simulation of conjugate heat
transfer is performed using an axisymmetric coordinate system. The Kistler contact line model is
used to determine the dynamic contact angle of a drop during spreading. The change in the shear
stress on the substrate and the heat flux induced during the propagation of the drop as a function
of time is studied.
