Abstract

A new simplified approach has been proposed toward coupling of the numerical simulation of transport phenomena in multiple regions in order to model complex domains. This approach is employed to study a tangential corotating twin-screw extrusion process. The flow domain in a twin-screw extruder is divided into the translation region (T region) and the intermeshing region (I region). The two regions are simulated separately and then coupled for each screw section, to model the overall transport. A finite difference method is employed in the T region, while a finite element method is employed for the/region. A procedure for coupling of the two flow regions is presented.
