Dip coating of fibers in the visco-inertial regime: numerical analysis

The dip coating of a fiber of small radius is studied via a finite element solution of the Navier-Stokes equations. The coating speed is selected within the range corresponding to the visco-capillary and visco-inertial regimes. Predictions obtained within the range of the visco-capillary regime are...

Sumario:The dip coating of a fiber of small radius is studied via a finite element solution of the Navier-Stokes equations. The coating speed is selected within the range corresponding to the visco-capillary and visco-inertial regimes. Predictions obtained within the range of the visco-capillary regime are in very good agreement with the Landau?Levich law and with published experiments, whereas those obtained within the visco-inertial regime--that is, at coating speeds typical of industrial applications--match published experimental data.
