| 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. The course will present the current state of art in the field. Challenging examples, mainly from the fluid-machinery and plant, are discussed in detail. | ||||
| Learning objective | Fundamentals of 3D multiphase flows (Definitions, Averages, Flow regimes), mathematical models (two-fluid model, Euler-Euler and Euler-Lagrange techniques), modeling of dispersed bubble flows (inter-phase forces, population balance and multi-bubble size class models), turbulence modeling, stratified and free-surface flows (interface tracking techniques such as VOF, level-sets and variants, modeling of surface tension), particulate and aerosol flows, particle tracking, one and two way coupling, random walk techniques to couple particle tracking with turbulence models, numerical methods and tools, industrial applications. | ||||
| 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. | ||||
| Learning 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. | ||||
