Abstract

Abstract Two-phase pressure drop, boiling heat transfer, and critical heat flux to water were studied in a small horizontal tube of 2.98-mm inside diameter and 0.91-m heated length. Experiments were performed at a system pressure of 200 kPa, mass fluxes of 50–200 kg/m 2s, and inlet temperatures from ambient to 80 °C. Experimental results and comparisons with state-of-the-art predictive correlations are presented. Modifications were made to the Chisholm two-phase multiplier correlation and to the Argonne National Laboratory small-channel boiling heat transfer correlation to better predict the experimental data of the present study.
