Nonisothermal newtonian film blowing

Abstract

In this paper, we refine Han and Park results for nonisothermal film blowing: we propose a correction in their temperature and force balance equations, and prove that with this change the actual system should be split into three other systems, and use a different scaling supposedly more suitable to find the solution of the equations. Besides all that, we also provide an analysis on how our nonisothermal model could improve modeling of the film blowing process. It is worth mentioning that, even though we have corrected (mathematically) the force balance equation by Han and Park, we only make use of the first version of the split model in our simulations to match the other simulations done with the model so far. Future work will include further refinements on the simulations.

Šiame straipsnyje tobulinami Hano ir Parko rezultatai apie neizotermini filmo juostos pūtima. Autoriai patikslina temperatūros ir jegu balanso lygtis ir irodo, kad tai išskaido lygčiu sistema i tris sistemas. Tai igalina rasti uždavinio sprendini. Taip pat pateikta analize kaip šis modelis, gali patobulinti pūtimo procesa. Kadangi naudojamas pataisytas Hano ir Parko modelis, todel modeliuojant gauti rezultatai ne visuomet sutampa su kitu eksperimentu rezultatais. Ateityje numatoma tobulinti šiuos eksperimentus.
