Transient fluid phenomena during a rapid two-phase depressurisation

Abstract eng:
Experiments were carried out using a custom-built facility to determine the loading on a model nuclear steam generator tube array during a simulated Main Steam Line Break accident. The working fluid was refrigerant R-l34a. Measurements were taken of temperature and pressure during the fluid transient and high-speed Videos from synchronised cameras were used to help understand the related flow physics. Sudden depressurisation was created using a rupture disc that opened fully in a few milliseconds. Parametric studies were undertaken to investigate the effects of varying initial conditions and liquid levels. The results provide valuable insights into the two-phase flow physics during such an event and have significant potential for benchmarking numerical code development as well as predicting tube loading.
