EXPERIMENTAL DATA SET NO. 12: ANNULAR FLOW EVAPORATION

ABSTRAKT

The experimental data of Bennett et al. (1966&1967), which studied the behaviour of the film flowrate over the full length of a channel with dryout occurring at the exit of the channel, are presented in this paper and are used to act as a basis in the sensitivity tests of the models. The annular flow model suggested by Whalley et al. (1972) give a rather accurate prediction of the dryout quality. However, there are large discrepancies in the prediction of the entrained flowrate in the upstream region of the channel, which is related to the inaccuracies in the prediction of entrainment rate by the correlations employed.
