Mathematical modelling of curtain coating

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”.
