Course Description

Single and multiphase flows and heat transfer with phase change are of interest to researchers and engineers working in all aspects of the nuclear industry. The course offered here is related to similar courses that have been offered in the past at Stanford University, the University of California-Santa Barbara and the ETH-Zurich but with greater emphasis on the thermal-hydraulic aspects of nuclear systems. The area continues to be of interest to generations of engineers with the ETH course having been offered continuously since 1984 with over 1500 participants. The course being offered in Washington DC continues this tradition and affords not only the opportunity to meet outstanding lecturers, but also colleagues working nationwide on similar topics.

The course is organized in a modular form with an intensive introductory part for participants having basic knowledge of fluid mechanics, heat transfer, and numerical techniques, but also with a second more specialized part that discusses the latest information and applications. A tutorial text is e-mailed to the participants before the course to introduce the very basic concepts to fill any gaps in background and help participation in the courses in the most productive ways.

Part I: Bases covers the common background material and emphasizes the latest modeling and computational aspects of single and multiphase flows in nuclear systems

Part II: Applications covers single and multiphase flow topics specifically of topical interest to nuclear systems. This part reviews, for example, recent developments with applications to design basis accidents, spent fuel cooling, steam generator tube rupture analyses, coupled neutronics-thermal-hydraulics, degraded core effects on long term cooling as well as beyond design basis accidents.

Part III: Computational Multiphase Fluid Dynamics (CMFD) presents the latest commercial and applications-oriented computer models as applied to nuclear systems.


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 nuclear industry applications
  • Trends in modeling, design, analysis, computational techniques, CFD / CMFD methods and experimentation
  • Sources of information, data and correlations
  • Availability as well as limitations of modern modeling and computational techniques and codes
  • Interdisciplinary transfer of knowledge from other areas of application to nuclear systems

This limited-enrollment course features:

  • A program of coordinated lectures by experts in the field in fundamentals and applications
  • A complete and extensive set of lecture notes in electronic form plus handout-format copies of all the standardized PowerPoint presentations
  • Videos, animations, and computer simulations illustrating the physical phenomena and numerical techniques
  • Discussion time and discussions with the lecturers during and between lectures
