Confirmation of the experimentally measured cooling time of Polyethylene Terephthalate (PET) melt by ANSYS and FORTRAN
Abstract
This study deals with confirmation of the experimentally measured cooling/solidification time of the Polyethylene Terephthalate (PET) melt by ANSYS and FORTRAN analysis programs. Therefore, a new code was written and run by using FORTRAN programming. With the ANSYS Thermal Transient module, cooling time and the injection conditions of PET into a cylindrical mold were simulated. Then, the experimental results and the analysis data were compared. It was determined that the results are in good agreement (100%) in case of heat capacity (Cp) value is chosen depending on the temperature. The results show that the proposed new codes will contribute to the optimization of cooling/solidification time for industrial scale PET production.

Polietilen Teraftalat (PET) eriyiğinin deneysel olarak ölçülen soğutma süresinin ANSYS ve FORTRAN tarafından doğrulanması
Abstract
Bu çalışma, Polietilen Tereftalat (PET) eriyiğinin deneysel olarak ölçülen soğutma süresinin soğutma/katılaşma süresinin ANSYS ve FORTRAN analiz programları tarafından doğrulanması ile ilgilidir. Bunun için, FORTRAN programı kullanılarak, yeni bir kod yazıldı ve çalıştırıldı. ANSYS Thermal Transient modülü ile soğutma süresi ve PET'in silindirik kalıba enjeksiyon koşulları simüle edildi. Sonrasında, deneysel sonuçlar ve analiz verileri karşılaştırıldı. Isı kapasite (Cp) değerinin sıcaklığa bağlı olarak seçilmesi durumunda sonuçların uyum içinde olduğu (%100) tespit edildi. Sonuçlar, önerilen yeni kodların endüstriyel ölçekte PET üretimi için soğutma/katılaşma süresinin optimizasyonuna katkıda bulunacağını göstermektedir.
