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...

Additional information
