The entrainment of Newtonian liquid films onto a vertical surface which is continuously withdrawn from a bath of the liquid is considered. A new theoretical treatment is presented which is significantly different from previous theories and which predicts accurately the relationship between the dimen

✦ Synopsis
The coating of pseudoplastic liquids onto a vertical surface continuously withdrawn from the liquid bath is considered. The problem is treated in a two-dimensional nonlinear approach incorporating the inertial effects. The model gives a relationship between the dimensionless f&m thickness, T, and the Capillary number. Ca, as a function of the fluid physical properties and the uarameteres of the power-law model. The comparison with the experimental data is satisfactory.
