İplik Bobini Kurutulması Prosesinde Sıcaklık Alanının Sonlu Farklar Yöntemi İle Belirlenmesinde Bazı Faktörlerin Çözüm Hassaslığına Etkisi
Abstract
Bu çalışmada, boyanmış yün iplik bobinlerinin içerisinden basınçlı sıcak hava geçirilerek kurutulması işlemi için bir matematiksel model ortaya konmuştur. Sunulan matematiksel model, kurutma problemini, içerisinde yün iplik bobinin efektif termofiziksel özellikleriyle birlikte, zorlanmış taşınım etkisinden kaynaklanan konvektif terimi barındıran nonlineer, nonstasionar bir ısı taşınımı problemine indirgemiştir. Matematiksel modelin çözümü için sonlu farklar metodu kullanılmıştır. Bu yöntemde uygulanan algoritmadaki uzay ve zaman adımlarının ve nonlineerliğin (ke(T), Cve(T)) sıcaklık alanına etkisi incelenmiştir.

Effect of Some Factors on Solution Sensitivity in Determination of Temperature Field by Finite Difference Method for the Drying Process of Yarn Bobbins
Abstract
In this study, a
mathematical model for the drying process of dyed wool yarn bobbins by passing
hot air through them has been presented. The presented mathematical model
reduced the drying problem to a nonlinear, nonstationary heat convection
problem including the convective effect caused by forced convection, together
with the effective thermophysical properties of the wool yarn bobbins. The
finite difference method was used for solving the mathematical model.
