Course content

The course is given every other year. Spring 2025 etc

The main content is basic aspects of detailed mechanistic modelling of multiphase flows for typical examples of such flows in technological context. Particular topics include: Conservation laws and interface conditions, averaging theorems, local and global forms, dispersed flow and turbulence, hydrodynamic interaction between phases, distributed effects in two- and three dimensions, waves and instabilities on interfaces, driftflux and two-fluid models, dynamic multiphase transport, heat and mass transfer in dispersed flows, granular flows, numerical treatment of free surface flows.

Learning outcome

Knowledge: Basic background of multiphase models for stratified, dispersed, and granular flow phenomena, mostly in technological context, both in 1-D and multidimensional settings. Limitations and range of validity of classical models, and current computational techniques for systems including turbulence models and interaction forces with bubbles, droplets, and particles. Heat and mass transfer during disperse flow. Numerical treatment of free-surface flows. Skills: Candidates are able to work with state of the art multiphase models, and with related numerical simulations, in a wide variety of problems from mechanical, metallurgical, chemical - and petroleum engineering. General competence: Understanding the basic mechanistic - and thermodynamic concepts behind typical multiphase models, and ability to apply this - along with current computational tools - to further research and development in science and technology.
