Abstract

We investigate the dewetting rates of thin liquid films using a lubrication model thatdescribes the dewetting process of polymer melts on hydrophobized substrates. We studythe effect of different boundary conditions at the liquid/solid interface, in particular, of theno-slip and the Navier slip boundary condition, and compare our numerical solutions forthe no-slip and the slip-dominated cases to available results that originate from scalingarguments, simplified flow assumptions and energy balances. We furthermoreconsider these issues for an extended lubrication model that includes nonlinearcurvature.
