Dyson, R. J. and Howell, P. D. and Breward, C. J. W. and Herdman, P. and Brander, J. (2005) Mathematical modelling of curtain coating. Proceedings of the 6th European Coating Symposium ECS2005 .
We present a simple mathematical model for the fluid flow in the curtain coating process, exploiting the small aspect ratio, and examine the model in the large-Reynolds-number limit of industrial interest. We show that the fluid is in free fall except for a region close to the substrate, but find that the model can not describe the turning of the curtain onto the substrate. We find that the inclusion of a viscous bending moment close to the substrate allows the curtain to “turn the corner”.
