Introduction to Multiphase Systems

Postgraduate course

Course description

Objectives and Content



The subject introduces multiphase systems in the processing industry. The course includes: momentum transport in and between continuous (fluid) and disperse (bubbles, drops or particles) phases, applications to multiphase flow phenomena, heat and mass transfer between continuous and dispersed phases applications (e.g. to contacting towers), chemical reaction with simultaneous transport of momentum, heat and mass between the phases, and applications to multiphase reactors.

Learning Outcomes

On completion of the course

the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
