Abstract
Bu çalışmada çözeltiden üfleme tekniği (Solution
Blowing Technique) ile üretilen nanoliflerin lif çapı ve morfolojisi üzerine uygulanan
hava basıncının etkisi hesaplamalı akışkanlar dinamiği (HAD) analizi ANSYS®
Fluent yazılımı kullanılarak incelenmiştir. Elde edilen HAD analizi sonuçları
daha önce gerçekleştirilen deneysel sonuçlar ile karşılaştırılmıştır. Bu sonuçlara
göre hava giriş basıncı 100 kPa’dan 300 kPa değerine çıkınca lif çapı azalmakta
ve lif morfolojisi daha düzgün olmaktadır. Ancak, aksine 300 kPa’dan 600 kPa
değerine çıkınca hem lif çapı artmaktadır, hem de türbülans yoğunluğu (TY)
arttığı için lif morfolojisinde topaklanmaların olduğu görülmektedir. 100 kPa
değerinde ise havanın polimer çözeltisini tahrik kuvvetinin yetersizliğinden
dolayı damlacıklı yapıların olduğu görülmüştür. Aynı şekilde bu çalışmada hava
basıncının etkisi sonlu hacimler metodu (SHM) ile incelenmiştir ve deneysel
veriler ile kıyaslanmıştır.
