Burnout Conditions for Round Tubes at Elevated Pressures

“…Employing these data and the Vanderwater [3] model for annular flow, Becker [2] developed a burnout correlation, which agreed very well with the data, and also with measurements obtained at other laboratories, for instance MIT [4], Harwell [5], Winfrith [6] and Columbia [7]. One of the most important features of the correlation was the demonstration that for a certain diameter and pressure, it was possible to correlate the data by plotting the local burnout steam quality x BO , versus the parameter (G 05 q/A)' 1 .…”

“…In Sweden about 4000 round-tube burnout measurements have been carried out at AB Atomenergi [1,2], covering the pressure range between 2.2 and 100 bar, and studying wide ranges of mass velocity, inlet subcooling, heat flux, diameter and heated length. Employing these data and the Vanderwater [3] model for annular flow, Becker [2] developed a burnout correlation, which agreed very well with the data, and also with measurements obtained at other laboratories, for instance MIT [4], Harwell [5], Winfrith [6] and Columbia [7].…”

“…( 3) Swedish data [25] for which the bundle shroud was h_eated and the CHF was reported to occur on the heated shroud. These data are considered to be nontypical of rod CHF as CHF occurred on the concave surface of the shroud as opposed to the convex surface of a rod.…”

“…Concerning Dr. Petrick's remarks about our 3-rod cluster data [24] obtained at the pressure of 4 kg/cm 2 , we would like to refer to Figs. 4 and 5 in that paper.…”
