Abstract
To investigate the effect of the Froude number (Fr) on solid segregation in a rotating drum, a two dimensional mathematical modelling on solids behaviour in horizontally oriented rotating drums operated in rolling, cascading and cataracting modes has been carried out by using Euler-Euler multi-fluid model in Fluent®6.2 environment. Small particles and big particles are used in the work as binary mixtures to investigate segregation characteristics. The effect of Froude number (rotating velocity) on the flow field is investigated. It is found that the model captures the main features of solids motion and segregation in the drum and numerical results agree well with limited experimental data for solid velocity.
