Description:
| Aims: To give students an introduction to the behaviour of particulate systems within a broad range of applications.
Learning Outcomes: After successfully completing this unit students should be able to:
* characterise particles by size, shape, and size distribution;
* calculate drag forces using standard correlations and determine particle trajectories;
* calculate terminal and equilibrium velocities for single particles and design and evaluate classifiers, elutriators and centrifuges;
* calculate sedimentation velocities for suspensions;
* calculate pressure drop in packed beds, describe the basic fluidisation phenomena;
* describe techniques for the storage and conveyance of particles and associated hazards;
* calculate filter performance for constant pressure and rate operation;
* describe the behaviour of fine particles and the electrical and surface effects that cause this behaviour.
Skills: Analysis, synthesis and design and creativity.
Content:
* Formation and characterisation of dispersed phases;
* Crushing and grinding;
* Fluid mechanics applied to deformable and non-deformable dispersed phases;
* Settler thickener design: precipitation and coalescence;
* Centrifugation: disk; decanter; solid bowl types;
* Packed and fluidised beds;
* Filtration;
* Pneumatic and hydraulic conveying and other methods of transport for solids and slurries;
* Colloids and emulsions;
* Agglomeration and flocculation.
