Modelling of viscouse incompressible fluid transfer with computer-generated graphics of the deformation in contact zone

Abstract

The results of numerical modelling including computer-generated graphics of deformation within a viscouse incompressible fluid layer at the transfer process onto a substrate between contacted cylinders are presented. The modelling is performed using developed algorithm of numerical calculation of Navie-Stocks evaluations for the viscouse incompressible fluidon a two-dimensional mesh grid by finite-difference methods with additional computation of moving borders taking to account fluid splitting, fluid microdrops formation and contacting surfaces deformation due to pressure difference. A laminar type of the viscouse incompressible fluidflow at a surfaces contact point incase of a permanent cylinder rotation
is considered. It is noted that the programm implementation of the developed algorithm as exemplified by a printing system allows to automate ink transаer coefficient estimation and also to predict printing system parameters.
