Multiphase Flows
Last Updated: 2026-02-05 15:54:30
Abstract
Introduction to fluid flows with multiple interacting phases. The emphasis is on regimes where a dispersed phase is carried by a continuous one: e.g., particles, bubbles and droplets suspended in gas or liquid flows, laminar or turbulent. The flow physics is put in the context of natural, biological, and industrial problems.
Objective
The main learning objectives are: - identify multiphase flow regimes and relevant non-dimensional parameters - distinguish spatio-temporal scales at play for each phase - quantify mutual coupling between different phases - apply fundamental principles in complex real-world flows - combine insight from theory, experiments, and numerics
Content
Single particle and multi-particle dynamics in laminar and turbulent flows; basics of suspension rheology; effects of surface tension on the formation, evolution and motion of bubbles and droplets; free-surface flows and wind-wave interaction; imaging techniques and modeling approaches.

General Electives (Students may choose General Electives from the entire course programme of ETH Zurich - with the following restrictions: courses that belong to the first or second year of a Bachelor curriculum at ETH Zurich as well as courses from GESS "Science in Perspective" are not eligible here. The following courses are explicitly recommended to physics students by their lecturers. (Courses in this list may be assigned to the category "General Electives" directly in myStudies. For the category assignment of other eligible courses keep the choice "no category" and take contact with the Study Administration ( ) after having received the credits.))
