A numerical model is presented for the simulation of cell emptying behaviour when an engraved roller is used to transfer a liquid coating onto a moving substrate. The threedimensional unsteady liquid motion is calculated where the ̄ ow domain is bounded above by a stress-free surface and bounded below by a moving substrate with a complex pattern of indentations. The physical model is simpli ® ed through use of the long-wave or lubrication approximation appropriate to ̄ ow in thin liquid layers… CONTINUE READING
