Next - generation modeling of melt blowing / Brent R. Shambaugh in Industrial & engineering chemistry research, Vol. 50 N° 21 (Novembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 21 (Novembre 2011) . - pp. 12233-12245 Titre : Next - generation modeling of melt blowing Type de document : texte imprimé Auteurs : Brent R. Shambaugh, Auteur ; Dimitrios V. Papavassiliou, Auteur ; Robert L. Shambaugh, Auteur Année de publication : 2011 Article en page(s) : pp. 12233-12245 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Modeling Résumé : An advanced model has been developed for predicting the behavior of a fiber as it is formed in the melt blowing process. The model involves the simultaneous solution of the momentum, energy, and continuity equations. Crystallization effects are included. The model equations are solved numerically. As a bottom boundary condition in this solution, a "stop point" is assumed. The stop point is the point where (a) the fiber stress is zero, and (b) the air velocity and fiber velocity are equal. Predicted parameters include fiber diameter, velocity, temperature, stress, and crystallinity. The predicted results show that very little online crystallization takes place under typical melt blowing conditions.
