Przedstawiono metodykę modelowania za pomocą systemu POLYFLOW problemu kształtowania strugi tworzywa wypływającej z kanału formującego, np. głowicy wytłaczarskiej (tzw. efekt Barusa) w odniesieniu do przepływów lepkich i lepkosprężystych w warunkach izotermicznych. Z tego punktu widzenia przeanalizowano model newtonowski, uogólniony model newtonowski (Birda-Carreau) oraz dwa modele lepkosprężyste...
The polymerization of a dimethacrylate monomer occurring in the dark after the initiating light has been switched off (so-called after-effect) was modeled by assuming of two different termination mechanisms: monomolecular (Model 1) and bimolecular (Model 2). Time dependent monomolecular termination (k(t)(m)) and bimolecular termination (k(t)(b)) rate coefficients and a time independent propagation...
