New Approach to Solve a Model for the Effective Solid Stress Distribution in Conical Spouted Beds
Charbel et al. (1999) have investigated the flow stability in conical spouted beds by modeling the effective solid stress distribution in the annular region as a function of the failure state under which the spout‐annulus interface is formed. However, due to the complexity in solving the momentum ba...

Summary: | Charbel et al. (1999) have investigated the flow stability in conical spouted beds by modeling the effective solid stress distribution in the annular region as a function of the failure state under which the spout‐annulus interface is formed. However, due to the complexity in solving the momentum balance equations for the solid phase, the model application has been restricted to one case. This work is aimed at developing a new methodology to solve this set of algebraic differential equations, using optimization techniques to determine the model parameter. This methodology has improved the model solution extending its application for any other case.
Charbel et al. (1999) ont étudié la stabilité d'un écoulement dans un lit à jet conique à travers la modélisation de la distribution effective de la tension solide dans la region annulaire comme fonction de l'état de rupture sous laquelle l'interface jet‐annulus est formée. Cependant, dû à la complexité de la solution des équations de conservation du moment pour la phase solide, l'application du modèle a été restreinte à une seule situation. Ce travail a pour objectif de développer une nouvelle méthodologie pour la solution d'un système d'équations différentielles algébriques utilisant une téchnique d'optimisation pour déterminer les paramètres du modèle. Cette méthodologie est un perfectionement du modèle qui permet une extension de la solution à d'autres cas. |
