Abstract

The results of numerical modeling of polymeric film formation under mass force action are presented. The instability of non-Newtonian liquid front edge at the initial stage of flow over a disk is studied. The quasi-stationary shape of the liquid film (in front edge vicinity) speading over the surface is determined for certain rheology laws. At the modeling of the second stage of coating flow, the special attention was paid to the effects connected with the two-dimensional character of the flow. The impact of rheological properties of a liquid on the free surface shape was studied using codes that calculate the two-dimensional non-stationary flow of non-Newtonian liquid. The factors that determine the final shape of polymeric coating free surface are discussed.
