Hydraulics and dispersed systems Unit Operations
Presentation
Programme (detailed contents):
- Basic concepts:
- Motion of particles, drops and bubbles in a fluid (various separation regimes, spherical and non spherical particles, concentrated media)
- fluid flow through a porous media (pressure drop, resistance)
- hydrodynamics of packed towers
- Unit operations:
- cake filtration
- sedimentation
- fluidisation
- Dimensional analysis
- Hydraulics:
- Linear and singular pressure drops
- hydraulic characteristics of a network, of a pump
- hydraulic networks
Objectives
At the end of this module, the student will have understood and be able to explain (main concepts):
- basic concepts of unit operations associated with momentum transfer phenomena for dispersed systems (bubbles, drops, particles)
- basic concepts of fluid flow (in pipes, through a porous medium)
- principle of dimensional analysis
- mass and energy balance
The student will be able to:
- design of different unit operations: sedimentation, filtration
- calculate the hydrodynamics of a packed tower, of a fluidised bed
- design of a pump, a hydraulic network
Needed prerequisite
I2BETF11 Transport phenomena and reactions in fluids
Form of assessment
The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
