Résumé

In this study, the transient pool boiling CHF (critical heat flux) for exponential heat generation rates with various periods for saturated and subcooled liquids at various pressures were investigated to clarify the effects of surface conditions such as commercially-available and roughly-finished surface cylinders in water, ethanol and FC-72. It was clarified that the trend of CHF for the shorter periods was significantly affected by the surface conditions.
