AbstractIntroduction 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.
ObjectiveThe 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
ContentSingle 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.
