Aim
The aim is to acquire knowledge within the field of particle technology including particle characterisation as well as particle interactions in different types of fluids in order to be able to identify and solve problems arising when handling particular material.

Knowledge and understanding
For a passing grade the student must

understand how the properties of the single particles influence their performance at particle characterisation and in flowing systems.
understand how the properties of assemblies of particles influence the characterisation of bulk of particles and particulate unit operations.
be able to define basic concepts within particle technology

Skills and abilities
For a passing grade the student must

be able to apply basic fluid dynamics on particulate flowing systems
be able to apply the knowledge of single particles and bulk material on a number of particulate unit operations
be able to present solutions of a problems in short written communications.
be able to present a small project orally and in a project report

Judgement and approach
For a passing grade the student must

be able to independently acquire and value information within an optional topic, which deals with a particulate problem.
