Many chemical unit operations (reactors or separators) contain multiphase flows, e.g. the polymerization of gaseous ethylene to solid polyethylene or the production of steel (liquid) in which bubbles are entrained during casting. Because of the limited optical access and problems with the in-situ measurements (temperature or pressure), multiphase Computational Fluid Dynamics (CFD) has gained more interest to improve and design these unit operations. This course is recommended for students who want to improve their knowledge on the simulation of multiphase CFD. The course will provide insight in the currently used models to simulate multiphase flows. To enable a good comparison of methods, the basics of CFD will be briefly discussed. By combining detailed understanding of the different techniques and the use of the different models, a student will be able to choose between the different models to simulate a multiphase flow problem.
Objectives
Students can distinguish between implicit and explicit discretization techniques.
Students can use/apply first and second order discretization schemes, given the limitations of these schemes.
Students can distinguish between continuum and discrete approaches.
The students can analyse the results of a multiphase Computational Fluid Dynamics code.
Students can perform grid/time step dependency studies.
Students can apply/distinguish Direct Numerical Simulation, Euler-Lagrangian and Euler-Euler type of models.
Students can select a proper multiphase Computational Fluid Dynamics model to simulate a certain problem.
