Abstract
The variations with flow rate of ‘apparent’ contact angles calculated from a 2-D finite element simulation of curtain coating are compared with experiments to illustrate the inadequacy of standard models. An improved wetting model featuring a variable dynamic contact angle is also tested and shown to give better agreement with experiments.
