Evaluation of the usefulness of the Friedel method for the calculation of the frictional resistance of two-phase flow in minichannels.

Ocena przydatnosci metody Friedel'a do obliczania tarciowego oporu przeplywu dwufazowego w minikanalach.

Author(s) : DUTKOWSKI K., BOHDAL T.

Summary

Results of experimental investigations of pressure drop in two-phase adiabatic flow in tubular minichannels are presented. Air-water mixture was used as a working fluid. It was found, on the basis of the experimental investigations, that the application of the Friedel method for the evaluation of pressure drop in the two-phase flow provided poor results. It is therefore necessary to make some corrections and modifications for two-phase flow in minichannel correlations.
