N2 - The interaction of a liquid drop with a copper surface is studied. The substrate is assumedto be superhydrophobic with a wetting angle of (Formula presented.). Based on the volume of the drop, the Bond and Weber numbers areapproximately 0.23 and 1.6, respectively. The temperature of the surface and the surrounding airis 298 K, and the temperature of the liquid drop is 5K lower. Simulation of conjugate heattransfer is performed using an axisymmetric coordinate system. The Kistler contact line model isused to determine the dynamic contact angle of a drop during spreading. The change in the shearstress on the substrate and the heat flux induced during the propagation of the drop as a functionof time is studied.
