TEACHING INTERESTS
Undergraduate courses in statistical methods, principles, application of statistics to process engineering, energy generation, consumption and environmental effects, mathematical modeling and application to mineral processing operations. Active in the development of on-campus Web course on these topics.
RESEARCH INTERESTS
Currently active in simulation of charge motion in tumbling mills with the discrete element method. Ultra fine particle production with high energy mills. Application of CFD to particulate processes. High-frequency eddy current separation of particles.
Modeling and simulation of mineral processing, comminution, ultrafine grinding.
Current Projects
- Mineral Processing: Discrete element method simulation of charge motion in tumbling mills -- The spring dashpot model of individual ball collisions is solved for impact energy spectra. A versatile three-dimensional code is under development for SAG and ball mills.
- Optimized Charge Motion and Slurry Flow in Plant-Scale SAG Mills. The cascading motion of charge and slurry flow through pulp lifters are examined for better energy efficiency.
- Environmental Cleaning: Separation of metallic granules from waste streams using a high-frequency eddy current device. An alternating magnetic field is generated in a ferrite core to bring about the separation.
- Computational Fluid Dynamics Applied to Hydrocyclones. Reynolds stress model and large eddy simulation features of FLUENT software are used in modeling hydrocyclones.
