Transition boiling heat transfer and the film transition regime
- Univ. of Houston, TX (United States)
The Berenson flat-plate transition-boiling experiment has been re-created with a reduced thermal resistance in the heater, and an improved access to those portions of the transition boiling regime that have a steep negative slope. Tests have been made in Freon-113, acetone, benzene, and n-pentane boiling on horizontal flat copper heaters that have been mirror-polished, roughened, or teflon-coated. The resulting data reproduce and clarify certain features observed by Berenson: the modest surface finish dependence of boiling burnout, and the influence of surface chemistry on both the minimum heat flux and the mode of transition boiling, for example. A rational scheme of correlation yields a prediction of the heat flux in what Witte and Lienhard previously identified as the film-transition boiling region. It is also shown how to calculate the heat flux at the boundary between the pure-film, and the film transition, boiling regimes, as a function of the advancing contact angle.
