Prerequisites
Not applicable
Objectives
The student should be able to calculate the basic design parameters for equipment used in milling/grinding/emulsification and particle/fluid droplet separations and to interpret the fluid flow hydrodynamics through particle beds.
Program
Grinding / Crushing and Emulsification:
- Types of Mills
- Grinding energy
- Area/volume relation and shape factor
Study of the particle motion behaviour within fluids - drag coefficient and Stokes law.
Equipment design for:
-Gravitational classification;
-Sedimentation;
-Centrifugation;
-Fixed and fluidized particle beds;
-Filtration.
Evaluation Methodology
Continuous assessment is carried out through
a written test and involves the answer to theoretical questions and practical questions about equipment design. The students that obtain a mark equal to or higher than 9.5/20 in the test will be exempted from taking the exam and pass the course.
Students eligible for the exam will pass if they reach a mimimum mark of 9.5/20.
