532.517.2:534.2Abstract
This work researches simulation of viscoelastic fluid creeping flow with free surface, which is realized at entrance and of polymeric fluid to the extrusion channel and it's exit from the channel. The flow of fluid is described by equations of mass conservation, momentum and energy, supplemented with rheological constitutive equation of Giesekus. The ratio of polymeric fluid extrusion effect in dependence of rheological model parameters, temperature factors, nozzle form are received.
