Abstract

Based on the simplified viscocapillary models for Newtonian and power-law coating liquids reported in Lee et al. (2011a), the one-dimensional (1-D) viscocapillary model for Carreau-type liquids containing zeroshear viscosity information has been developed for constructing the operability window in slot coating. Velocity distribution and position of upstream meniscus were numerically solved to determine onsets of leaking and bead break-up defects. The results obtained by 1-D model are quantitatively corroborated by two-dimensional (2-D) fluent calculations.
