Résumé

Experimental results of adiabatic two-phase pressure drop in micro/minichannels for both multi- and single-channel configurations were obtained from the literature. The collected database contains 769 data points, covering 12 fluids, for a wide range of operational conditions and channel dimensions. The whole database was analyzed using eleven existing correlations to verify their respective accuracies. In addition, the Bond number and the Reynolds number were introduced to modify the Chisholm parameter of two-phase multipliers to develop new generalized correlations. A particular trend was observed with the Bond number that distinguished the data in three ranges, indicating the relative importance of surface tension. [Reprinted with permission from Elsevier.
