Multiphysics Modeling Simulation and Optimization of Aerodynamic Drum Magnetic Separator

Aerodynamic Drum Magnetic Separator (ADMS) uses an adjustable air flow to enhance the separation of magnetic particles from gangue. In order to explore the matching relationship between the magnetic field, the flow field, and the gravity field, as well as the capture and separation behavior of parti...
