, 2015 The critical heat flux (CHF) condition is characterized by a sharp reduction of the local heat transfer coefficient as a result of the replacement of liquid by vapor adjacent to the heat transfer surface [1]. The CHF condition in flow boiling can be of different nature [1–5].

Critical Heat Flux in Tubes With Cosine Axial Heat Flux
Heat Transfer: Volume 2, 2005In this study a method to predict CHF (Critical Heat Flux) in vertical round tubes with cosine heat flux distribution was examined. For this purpose a uniform correlation, based on local condition hypothesis, was developed from 9,366 CHF data points of uniform heat flux heaters.

Abstract Studies of the critical heat flux (CHF) carried out during the last decade have been reviewed, with emphasis on the main current of investigation flowing steadily toward a better and “unmysterious” understanding of the CHF phenomenon, together with a survey of a number of fundamental studies on the CHF. In order to attain this objective and,

The critical heat flux is the heat flux at which a transition from nucleate to film boiling occurs. It is of interest to designers because a marked reduction in heat transfer results from the transition, which may be rather sudden and which is accompanied by a substantial rise in surface temperature. Knowledge of the critical heat flux dictates whether

Spreading of critical heat flux region during testing for onset of critical heat flux
Annals of Nuclear Energy, 1989Abstract Testing to determine the conditions that result in the onset of critical heat flux when the heat flux is not uniform has been enhanced by the implementation of a computerized power control system. Detection of the temperature increase in test rods that results from the onset of critical heat flux permits termination of the test prior to ...

Critical heat flux thermodynamics
Fusion Engineering and Design, 2002Convective boiling in subcooled water flowing through a heated channel is essential in many engineering applications where high heat flux need to be accommodated, such as in the divertor plates of fusion reactors. There are many available correlations for predicting heat transfer in the individual regimes of the empirical Nukiyama boiling curve ...
