Numerical simulations of two-dimensional curtain coating were performed using VOF method in order to find operational conditions of coating processes. The curtain shape was dependent on the flow rate of liquid, the viscosity of liquid, and the moving speed of a substrate. The results reproduced the previously obtained coating window which represented five regimes of coatable, uncoatable, heel formation, air entrainment, and heal formation with air entrainment. Formation of the curtain and its
