DEM Simulation and Analysis of Seeds Supply by the Vibrating Seed Box of Magnetic Cylinder Seeder
Regarding the vibrating seeds box of magnetic cylinder seeder as the research subject and making simulation and analysis for the motion law of seeds which supplied by seed box base on DEM (Discrete Element Method). Researching the mechanism of the seed supply and analyzing the condition of seed supply by the vibration of seed box, when the frequency change from 10Hz to 50Hz and horizontal and v...
متن کاملDEM-CFD modeling and simulation of granular systems
Size reduction process is widely used in the chemical and pharmaceutical industries. Jetmill is one of the most commonly used tool for such processes due to advantages they over other mills such as low contamination and narrow product size distribution. However the efficiency of the jet milling process is very low, furthermore the jet-milling process is sensitive to many parameters such as feed...
متن کاملCfd Simulation Of Flow Field In An Inject Pipe Mixer
The Inject Pipe Mixer (IPM) are being used as venturi injectors and can also homogenize two fluids. The entry of secondary fluid as a jet influences flow field in the device. A CFD simulation of flow through an IPM (Lshape) has been carried out using ANSYS CFX 11.0 using water as the flowing fluid to understand the flow field under turbulent flow conditions using standard k--ε model. The result...

15 صفحه اولThree-dimensional DEM–CFD analysis of air-flow-induced detachment of API particles from carrier particles in dry powder inhalers
Air flow and particle-particle/wall impacts are considered as two primary dispersion mechanisms for dry powder inhalers (DPIs). Hence, an understanding of these mechanisms is critical for the development of DPIs. In this study, a coupled DEM-CFD (discrete element method-computational fluid dynamics) is employed to investigate the influence of air flow on the dispersion performance of the carrie...
