Abstract

In the field of industrial inkjet marking, the drying time to evaporate the solvent is a key factor of the process productivity. In order to optimize it, a new approach of the drying process is assessed numerically in this paper. An air blade is used to push away  the newly evaporated solvent to reduce the local solvent partial pressure. Therefore, it maximizes the vaporization flux. This idea  is implemented within the software COMSOL Multiphysics®. The air flow is computed through the Navier-Stokes equation, and the solvent concentration is modelled by a convection-diffusion equation. The vaporization profile is assessed in several configurations. Eventually, the numerical results show that the air blade reduces dramatically the drying time. By this way and given a drying time in industrial environment, one can consider a broader family of solvent, i.e. less volatile solvent compared to so called MethylEthylKetone.
