Coupling dense and dilute granular flows in a high shear Mi-Pro granulator

摘要: A multi regime system has been modelled in a high-shear MiPro granulator using the EulerianEulerian framework. The rheology of granular material studied applying Kinetic Theory Granular Flow (KTGF) for dilute regimes and model dense (Jop et al., 2006). Experimens were conducted to validate study accuracy model. velocity profiles successfully obtained high speed camera PIV analysis. In general, highest values both tangential axial found region neighboring impeller blades, showing that distribution depends on position. partial slip conditions at boundaries also evaluated based experimental data. An over–prediction was found; however, shown an improvement making it good replacement Schaeffer’s extension KTGF regimes.
