Finite Diference Approximation of the System Transport Equations Ink between Rotating Cylinders
In this paper used the finite-difference approximation of the system of Navier–Stokes equations for simulation of the process of the transfer of ink (viscous incompressible fluids) between rotating cylinders of the printing machine of sheet offset machines with the use of calculating the motion of curvilinear boundaries of the liquid, both free and borders with cylinders. The program realization of the developed algorithm for numerical modeling provides a quantitative assessment of the coefficient of the splitting of the paint layer on the exit from the zone of the printing of contact for specifically defined components of the printing system «machine – printing ink – printed material» which will allow to predict consumption of inks for printing.
