Contact angle hysteresis (CAH) is a significant factor affecting the drop motion on solid substrates. A model of CAH is introduced to explore the influence of CAH on the dynamics of a sessile drop on a uniformly heated surface. and a two-dimensional evolution equation of the drop thickness is established using the lubrication approximation and Navier slip boundary conditions.
