TL;DR: In this article, a new general correlation for forced convection boiling has been developed with the aid of a large data bank consisting of over 4300 data points for water, refrigerants and ethylene glycol, covering seven fluids and 28 authors.

Journal ArticleDOI
TL;DR: The authors showed that the eonvective term in the correlation should have a Prandtl number dependence and constructed an accurate predictive method with an explicit nucleate boiling term and without boiling number dependence.

Journal ArticleDOI
TL;DR: In this paper, an extensive series of measurements of gas bubble diameters on detachment into flowing liquids has been performed and new expressions were proposed for the surface tension and drag forces experienced by a bubble attached to a solid surface.

Journal ArticleDOI
TL;DR: This article showed that contact angle has a very strong influence on transition boiling, improved wetting giving increased heat flux at a given superheat, provided a consistent method is used to roughen the surface then roughening improves the nucleate boiling heat transfer.

Journal ArticleDOI
TL;DR: In this article, the heat flux into the boiling liquid is calculated from temperatures at two levels using an inverse heat conduction solution, and the heat transfer is strongly affected by the value of the liquid contact angle, lower contact angles giving higher heat fluxes.

TL;DR: In this article, a simple correlation was developed earlier by Kandlikar (1983) for predicting saturated flow boiling heat transfer coefficients inside horizontal and vertical tubes, which was further refined by expanding the data base to 5,246 data points from 24 experimental investigations with ten fluids.
Abstract: A simple correlation was developed earlier by Kandlikar (1983) for predicting saturated flow boiling heat transfer coefficients inside horizontal and vertical tubes. It was based on a model utilizing the contributions due to nucleate boiling and convective mechanisms. It incorporated a fluid-dependent parameter F{sub fl} in the nucleate boiling term. The predictive ability of the correlation for different refrigerants was confirmed by comparing it with the recent data on R-113 by Jensen and Bensler (1986) and Khanpara et al. (1986). In the present work, the earlier correlation is further refined by expanding the data base to 5,246 data points from 24 experimental investigations with ten fluids. The proposed correlation gives a mean deviation of 15.9 percent with water data, and 18.8 percent with all refrigerant data, and it also predicts the correct h{sub TP} versus x trend as verified with water and R-113 data yielded the lowest mean deviations among correlations tested. The proposed correlation can be extended to other fluids by evaluating the fluid-dependent parameter F{sub fl} for that fluid from its flow boiling or pool boiling data.

Abstract: ▪ Abstract This review examines recent advances made in predicting boiling heat fluxes, including some key results from the past. The topics covered are nucleate boiling, maximum heat flux, transition boiling, and film boiling. The review focuses on pool boiling of pure liquids, but flow boiling is also discussed briefly.

Journal ArticleDOI
TL;DR: In this paper, the authors measured and predicted saturated flow boiling heat transfer in a water-cooled micro-channel heat sink and found that the dominant heat transfer mechanism is forced convective boiling corresponding to annular flow.
