TLDR
In this article, a regression analysis was applied to the nearly 5000 existing experimental data points for natural convection boiling heat transfer, which can best be represented by subdividing the substances into four groups (water, hydrocarbons, cryogenic fluids and refrigerants) and employing a different set of dimensionless numbers for each group of substances.About:

Heat Flow Rates in Saturated Nucleate Pool Boiling-A Wide-Ranging Examination Using Reduced Properties
TL;DR: In this article, the authors present the experimental data with no particular theory, to search for significant effects of physical parameters, finding a reason for the fact that they are often numerically similar, despite using very different properties that leads to the improved method of analysis.
Journal ArticleDOI
Boiling heat transfer
TL;DR: In this paper, a review examines recent advances made in predicting boiling heat fluxes, including some key results from the past, including nucleate boiling, maximum heat flux, transition boiling, and film boiling.

Small circular- and rectangular-channel boiling with two refrigerants
T.N. Tran,M.W. Wambsganss +1 more
TL;DR: In this article, a small circular channel (d = 2.46) and a small rectangular channel with Refrigerant 12.5 was used to study the effects of channel geometry and fluid properties on heat transfer.

Flow Boiling Heat Transfer in Vertical Tubes Correlated by an Asymptotic Model
Dieter Steiner,Jerry Taborek +1 more
TL;DR: In this article, a new model, based on asymptotic addition of the two boiling components, is introduced It follows the established principles of flow boiling and converges correctly to the extremes of all parameters Tested on the University of Karlsruhe data bank containing over 13,000 data points in vertical flow boiling, results superior to previous correlations are demonstrated

Heat Transfer Mechanisms During Flow Boiling in Microchannels
TL;DR: In this paper, the authors analyzed the forces due to surface tension and momentum change during evaporation in microchannels and derived two new non-dimensional groups, K1 and K2, relevant to flow boiling.

Experiments on pool-boiling heat transfer
TL;DR: In this paper, the authors measured the characteristic pool-boiling curve for n-pentane at atmospheric pressure as a function of surface roughness, material and cleanliness, and concluded that transition boiling is a combination of unstable nucleate and unstable film boiling alternating at any location on the heating surface.

The effects of superheat and surface roughness on boiling coefficients
H. M. Kurihara,J. E. Myers +1 more
TL;DR: In this article, the effects of surface roughness on boiling coefficients were investigated in a series of experiments in which water, acetone, n-hexane, carbon tetrachloride, and carbon disulfide were boiled on a flat plate.

Heat transfer in cryogenic liquids under pressure
TL;DR: In this article, the authors studied the dependence of the heat transfer on pressure for a horizontal plane surface in liquid helium, liquid hydrogen, and liquid nitrogen in the range 0.03 to 0.

Latent heat transport in saturated nucleate boiling
C.J. Rallis,H.H. Jawurek +1 more
TL;DR: In this article, the latent heat transport and convection together account for the total flux in saturated boiling, and the basic parameters entering into the formulation of (q/A)LH, that is, the product of bubble frequency and bubble volume at departure, are further investigated.
