JMBC Course : Multiphase flow (with heat transfer)

For single-phase flow CFD (Computational Fluid Dynamics) has reached such a level that it is now often used for design and operation of complex geometries of industrial interest. Thanks to our current capabilities of turbulence modelling, numerical techniques for complicated flow equations and grid generation of complex geometries the quality of the results of computer simulations has been improved dramatically. The ERCOFTAC Best Practice Guideline for industrial Computational Fluid Dynamics serves as an excellent vehicle to transfer technology from universities to engineers industry. For dispersed multiphase flow in wall-bounded equipment the level of complexity is enhanced dramatically. Still, also here for CFD interesting opportunities of industrial interest are available. The aim of the course is to address the possibilities and limitations of CFD for Dispersed Multiphase Flows. To assess the capabilities of computer simulations for flow geometries of industrial interest we will review the options for dispersed multiphase flows in tubes, fluidized beds, bubble columns, cyclones and stirred tank reactors. A common complication is that we have to deal with turbulence affected by walls and by particles. The latter can be bubbles, drops or solid particles, each with their own pecularities.

At the end of the course the participants will have an idea on what can be used with which accuracy for CFD of dispersed multiphase flows in industry. Since they will also get an insight into the current limitations for the industrial flow geometries discussed it will help them to assess realistic expectations for their practical problems, which undoubtedly will often be still more complex than the examples treated here.
