Numerous correlations for the minimum film boiling temperature have been published, but non have been shown to apply to a great variety of liquids. Based on the behavior of liquid droplets coming into contact with a hot surface, Olek et al. (1988) proposed that the rewetting temperature corresponds to very small liquid-solid contact angles. A relation by Adamson (1973) between the contact angle and the temperature was then used to determine the rewetting temperature for water on several polymeric surfaces. Adamson observed that the results he obtained for the temperature corresponding to a zero contact angle often lie in quite a narrow range around the geometric mean of the normal boiling point and the critical temperature of the liquid. Adamson's suggestion, together with the authors argument about the fact that the rewetting temperature corresponds to small contact angles, led us to examine whether Adamson's proposal can be used as a simple correlation for the minimum film boiling temperature.
