Part IIA: New Reactor Systems and Methods
Part IIB: Computational Multi-Fluid Dynamics (CMFD)
Part III: CMFD with Commercial Codes

Zurich, 10-14 February 2014

Swiss Federal Institute of Technology(ETH)

in Zurich, Switzerland


Multiphase flows and heat transfer with phase change are of interest to researchers and engineers working in power, nuclear, chemical-process, oil-and-gas, cryogenic, space, food, bio-medical, micro-technology, and other industries. Courses similar to this one have been offered in the past at Stanford University, the University of California-Santa Barbara and elsewhere. These courses have taken place annually at ETH-Zurich since 1984 with some 1600 participants so far. Over the years, the courses have continuously evolved, reflecting on-going progress and developments; the number of lecturers has gradually increased. The Zurich courses not only offer the opportunity to meet and interact with outstanding lecturers, but also with colleagues working worldwide on similar topics but possibly in different industries.

The courses are organized in a modular form as intensive introductory courses for persons having basic knowledge of fluid mechanics, heat transfer, and numerical techniques, but also serve as advanced courses for specialists wishing to obtain the latest information. A tutorial text is e-mailed to the participants before the course to introduce the very basic concepts and fill any basic gaps in their background, to help them participate in the courses the best possible way.

Part I, Bases, covers the common background material and emphasises the latest modelling and computational aspects of multiphase flows.

Part IIA, New Reactor Systems and Methods, covers multiphase flow topics of particular interest to nuclear engineers. This module reviews some of the most recently proposed advanced reactor designs (including reactors considered for near-term construction and those in Generation IV) and some of the multiphase phenomena of importance in these designs. This module also introduces the state-of-the-art and beyond in modelling and simulation methods for core design and accident analysis.

Part IIB, Computational Multi-Fluid Dynamics (CMFD), reflects the growing interest in the application of CFD techniques to multi-phase flows; it is continuously updated to cover the most common new computational techniques. The introductory chapters from a book authored by Tryggvason, Scardovelli and Zaleski will be emailed to the participants in Part IIB to prepare them for the lectures.

Part III, CMFD with Commercial Codes, is attached to both Parts IIA and IIB. The participants will have the possibility to meet commercial code developers and discuss their products for both nuclear and other applications.

Course Language: English

Lecturers: S. Banerjee, D. Bestion, M.L. Corradini, G. Hetsroni, G.F. Hewitt, D. Lakehal, Simon Lo, B. Niceno, H.-M. Prasser, G. Tryggvason, S.A. Vasquez, G. Yadigaroglu and S. Zaleski.

NB: Following the short courses, but independently, ASCOMP GmbH is offering training on its TransAT code on Saturday February 16, on a first-come first-served basis (number of participants limited to 25).
Please indicate your interest on the registration form and you will receive confirmation from ASCOMP.

The emphasis in these courses is on:

  • A condensed, critical and updated view of basic knowledge and future developments, in relation to systems and phenomena encountered in industrial applications
  • Trends in modelling, design, analysis, computational techniques, CFD / CMFD methods and experimentation
  • Sources of information, data and correlations
  • Availability as well as limitations of modern modelling and computational techniques and codes
  • Interdisciplinary transfer of knowledge from one area of applications to another

These limited-enrolment courses feature:

  • A program of co-ordinated, 90-min lectures by experts in the field
  • A complete and extensive set of the lecture notes and other non-copyrighted course materials on a CD-ROM
  • Handout-format hard copies of all the standardized PowerPoint presentations for use in the classroom (it is not advised to bring laptops)
  • Movies, videos, animations, and computer simulations illustrating the physical phenomena and the numerical techniques (with non-copyrighted material included in the CD-ROM)
  • Discussion time and discussions with the lecturers during and between lectures
