3D Numerical Modelling of a Dip-coating Process by a Multidomain Macroscopic Approach

Abstract : The hot dip-coating process is numerically studied on the bases of a 3D strongly coupled thermomechanical model. At the macroscopic scale, the process is described as a solidification of a hot Newtonian polymer solution on the surface of a cold mould moving in/out of the bath. The evolution of the temperature of the liquid around the mould and of the thickness of solid phase is governed by equations resulting from thermomechanics. The prediction of the solidified phase thickness is ensured by using a characteristic function which reflects the state of the solution (liquid or solid). A mixed finite element method with multidomain approach is developed in order to simulate the average growth rate of solidified layer during the dip-coating process and to characterize the influence of the velocity of the mould motion on its the thickness.
