What is the proper drag coefficient for a fluidized modelling?

01 January 2014 1 4K Report

I am trying to model a fluidized reactor (with fluent). When I am looking at articles different people use different drag models. In fluent there are a long list of different drag models (Schiller-Numann, Morsi-Alexander and etc.). What I am wondering is if anyone knows an article or maybe a book that explains how to decide what to choose as a drag model and why to choose it.

Hi,

see this work - you have there a review of models for fluidized beds:

Sobieski W.: Momentum Exchange in Solid-Fluid System Modeling with the Eulerian Multiphase Model. DRYING TECHNOLOGY, Vol. 27, No. 5 (2009), pp. 653-671. ISSN 0737-3937.

Regards,

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
