Phenomenological modelling of film-dryout ‘critical heat flux’

Abstract

This paper addresses the topic of phenomenological analysis of film dryout in the context of high quality critical heat flux in a nuclear reactor. It seeks to record the major contribution made to the subject by Geoff Hewitt over many decades, to report some recent advances, and to identify areas where improvement is still needed. It closes with a discussion of what future advances are to be expected.
