151-0170-00L | Computational Multiphase Thermal Fluid Dynamics | 4 credits | 2V + 1U | F. Coletti, A. Dehbi, Y. Sato | |

Abstract | The course deals with fundamentals of the application of Computational Fluid Dynamics to gas-liquid flows as well as particle laden gas flows including aerosols.

151-1906-00L | Multiphase Flows | 4 credits | 3G | F. Coletti | |

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. | ||||

Lecture notes | Lecture slides are made available. | ||||

Literature | Suggested readings are provided for each topic. | ||||

Prerequisites / Notice | Fundamental knowledge of fluid dynamics is essential. |
