Course motivation

The discipline of Computational Fluid Dynamics (CFD) involves the analysis of fluid flow and related phenomena such as heat and/or mass transfer, mixing and chemical reaction using numerical solution methods. Due to the rapid advances in CFD and the potential it provides to analyze, on a fundamental basis, systems of considerable interest to the chemical engineer, it can be anticipated that the importance of CFD as a “workhorse” for the chemical engineering community will rapidly increase in the near future.

Goal of the course

With this course we intend to provide detailed knowledge on the physical foundation of multiphase flow models and the associated numerical solution methods. Due to its relevance for many industrial applications the emphasis during the course will be on dispersed multiphase flows. The course includes hands-on computer sessions in which several in house simulation tools will be used to solve complex multiphase fluid flow problems.
