  • Basing on the Volume of Fluid(VOF) model of Computational Fluid Dynamics(CFD),the 3-D numerical simulation of the idling furnish roll in the producing process for color-coated sheet was performed with the FLUENT software. And the effects of some parameters on the uniformity of coatings were analyzed,such as the rotation speed of furnish roll,the amount of lacquer in the plate,the size of lacquer plate,the inlet and outlet locations of lacquer plate and the inlet velocity of the lacquer. For producing the color-coated sheets,numerical results show that the uniformity of coatings becomes worse as the rotation speed of the furnish roll increases; the higher the lacquer height in the plate is,the easier it emerges foams; the uniformity of coatings becomes better as the length and width of lacquer plate increase; the ability of producing the foams becomes stronger as the inlet velocity increases; the inlet and outlet locations of lacquer plate also influence the uniformity of coatings.
