Abstract Details

1990, Doctor of Philosophy, Case Western Reserve University, Chemical Engineering.
A fluid dynamics analysis package – FIDAP using the finite element method was implemented to simulate the flow patterns in a Banbury mixer. The flow simulations were carried out initially for the intensive mixing region of a Banbury mixer and they were limited to a two-dimensional analysis. A Lagrangian point of view was adopted and 18 different geometries were selected to represent one revolution of the rotor. A power-law model with time and temperature dependent parameters was used to characterize the rheological behavior of the mixture. The results of the analysis show good agreement with experimental observations regarding the pressure distributions and temperature profiles. The flow analysis was then extended to the entire mixing chamber with two counter-rotating rotors. This time, an Eulerian point of view was adopted. The flow simulations were limited again to a two-dimensional analysis, under the assumptions of pseudo steady-state and isothermal conditions. Streamline contours and velocity profiles indicating the material exchange between the two chamber lobes on the bridge region, as well as the obtained dynamic pressure profiles are in agreement with reported experimental observations. The simulation results were used to characterize the flow field in terms of a parameter quantifying the elongational flow components. The influence of design and processing variables on the flow characteristics as well as on the average shear rate were analyzed.
