Ivitskyi I. Wall Effects in the Process of Polymer Flow in Processing Equipment Channels

The dissertation is devoted to research presence, the nature and value of wall effects arising from the melt flow channels in polymer materials processing equipment. The method of determining the presence of wall effects polymeric material and the nature of these effects. Depending of the nature of wall effects developed methodology for determining the value of these effects in the material. Mathematical model of current polymer materials supplemented into account the effects of wall, depending on their nature and the material allowed us to create a universal approach to determining process parameters during the current numerical modeling. It was examine a numerical study of the influence of geometrical parameters of channel differences pressure between the absence of speed on the wall and consideration of wall effects. On the basis of empirical studies deduce equations to take into account when designing shelving effects without additional processing equipment of numerical studies.
