Revisiting the Corresponding-States-Based Correlation for Pool Boiling Critical Heat Flux

A corresponding-states correlation for predicting the critical heat flux (CHF) in pool boiling conditions is proposed, and only requires knowledge of physical property constants fluid at any temperature: molar mass, temperature, pressure, Pitzer acentric factor. If a fourth corresponding equation state (EoS) parameter added, more accurate CHF obtained matches Kutateladze–Zuber prediction within ±10% reduced temperature range 0.55–0.95. This way, can be easily predicted correlation’s validity by knowing basic properties fluid. Additionally, two correlations determining capillary length are proposed also do not rely on temperature- pressure-dependent properties. simpler using factor shown to imprecise, complex accounting EoS recommended. These fundamental further developments, which would allow values functionalized surfaces through studies influence interactions with other parameters, such as wetting active nucleation site density.
