“…Thus, CHF of other fluids could be predicted using the water data from look-up tables. An example of this approach is the one by Ahmad and Groeneveld [11], who showed agreement between R-12 and water data using this technique. There does not appear to have been a comprehensive comparison of any of the fluid-to-fluid modeling techniques with a wide range of data for annuli.…”

“…Gambill [2] found that his correlation greatly overpredicted CHF for gaps smaller than 2 mm. Hung and Yao [35] found the analytical correlation of Ahmad and Groeneveld [11] to greatly overpredict their data for annular gaps of 0.3 to 2.6 mm. As seen in Table 3, the Katto correlation [3] also greatly overpredicts these data of Hung and Yao.…”

A general correlation for critical heat flux (CHF) in uniformly heated vertical annuli with upflow is presented. It is an improved version in equation form of the author's 1980 graphical correlation. The correlation is compared to test data from 58 data sets from 25 studies. The data include annuli with internal, external, and bilateral heating, 10 fluids, reduced pressures from 0.016 to 0.905, flow rates from 100 to 15,759 kg/m 2 -s, tube diameters from 1.5 to 96.5 mm, annular gaps from 0.3 to 16.5 mm, ratio of length to heated equivalent diameter from 1.3 to 394, inlet qualities from -3.3 to +0.91, and critical qualities from -2.7 to +0.95. All data points are predicted with a mean absolute deviation of 16.5%. No other well-verified general correlation is available. Considering the good agreement with this wide range of test data, this correlation should be of considerable help in design and analysis.

“…Refrigerants such as Freon have been used in previous experiments (Refs. [64][65][66][67] to simulate water cooling at high heat flux conditions since the CHF for Freon can be achieved at much lower heat flux. Scaling methods were necessary to provide a means of relating the Freon test results to water for high heat flux/water cooling predictions.…”
