Outline for Two Day Multiphase Flow Course to be presented by

Dr. Paul Guilbert, ANSYS CFX
The course will cover the basic theory of Multiphase Flow (MPF) in a manner that is non-code specific but will draw examples from both ANSYS CFX and ANSYS FLUENT. The outline of the course is as follows:

 

1. MPF introduction (modelling approach, challenges, phase equation)

 
2. Eulerian Approach

2.1 Description of options, additional forces, sources, etc.

2.2 Turbulence modelling in multiphase phase models

2.3 Condensation (wet steam model, film & droplet condensation) & boiling (cavitation, thermal phase change, film boiling, RPI boiling)

2.4 Solids modelling, dense packing, kinetic theory models etc.

2.5 Free surface modelling, VOF, surface tension, contact angles, etc.

2.6 MUSIG model, population balance etc.

 

3. Algebraic Slip Model

3.1 Describe basic equation, limitations.

3.2 Show how it is set up and used

 

4. Lagrangian (Discrete particle) Approach

4.1 Basic equations, forces, heat transfer etc.

4.2 Droplet breakup

4.3 Droplet evaporation & combustion

 

5. Practical Examples

5.1 Gas-liquid system (typical applications of this are: bubble columns, tank sloshing)

5.2 Gas-solid system (typical applications of this are: fluidized beds for catalytic cracking, coal/ biomass gasification, packed bed reactor)

5.3 Stirred tanks with reaction & settling (typical applications include crystallizers, polymer production, precipitators etc)

5.4 Slurry transport through pipes etc.

5.5 Use of the wet steam model for non-equilibrium condensation in turbines

5.6 Sedimentation in settling tanks etc.
