Learning outcomes

On successfully completing this module, students will be able to:

  • Learning outcome 1

Module syllabus

Basics of single phase flow and heat transfer (pressure drop, regimes of heat transfer, prediction of heat transfer in smooth and rough channels etc).
Single phase heat transfer and fluid flow.  Prediction of heat transfer both within and from nuclear fuel cooled with a single phase fluid (e.g. in a Pressurised Water Reactor).
Basis of two-phase flow (regimes, models, pressure drop, critical flow etc) and two-phase heat transfer (boiling, critical heat flux, post-dryout heat transfer, reflood etc).
Application of two-phase flow and heat transfer theory to fuel design.  Critical heat flux prediction in fuel.
Typical nuclear reactor safety codes (for example TRACE).
Application of Computational Fluid Dynamics (CFD) to nuclear reactor systems.
