Learning outcome

A candidate who has completed the course will have a learning outcome in the form of acquired knowledge, skills, and general competence, as described below.

Knowledge

The candidate is mastering advanced theory and scientific methods regarding:

• fluidization; including characterization and classification of particles
• bubbling fluidized beds including gas-particle modelling and scaling
• particle circulation systems including risers and pneumatic transfer
• measurement systems for gas-particle flow

Skills

The candidate can plan and conduct research and development independently on gas-particle flow systems.

General competence

The candidate is able to communicate R&D results from studies where gas-particle multiphase flow plays a key role in recognised international channels.

Course Description

• Fluidization and mapping of regimes: characterization and classification of particles, effect of particle size distribution, effective sphericity, fluidization properties, particle-fluid interaction, particle-particle interaction (CK1, CS1, CG1)
• Bubbling fluidized bed: experimental findings, estimation of bed properties, physical models for scaling, flow models for bubbling beds, bubble formation, coalescence and splitting of bubbles (CK2, CS1, CG1)
• Circulation systems: circuits for circulation of solids, circulation rates, flow of gas-solid mixture in downcomers and risers, flow in pneumatic transport lines. (CK3, CS1, CG1)
• Experimental methods; sampling and measurement methods (CK4, CS1, CG1)
• Transport equations, one dimensional steady gas-solid flow, fluidized state (kinetic energy dissipation, drag models), origin of bubbles (bubbling criterion; equations), inviscid multiphase flows (bubbling beds). (CK1, CK2, CK3, CS1, CG1)
