Pressure Drop Characteristic of Flow Boiling in Narrow Rectangular Channel Under Rolling Motion
摘要
Abstract
Experimental investigation and analysis of the pressure drop characteristic of flow boiling in narrow rectangular channel were conducted under rolling motion. Several correlations for the two-phase frictional pressure drop were evaluated against the experimental data. The results show that the correlations for conventional channel poorly predict the results. While the Zhang-Mishima and Sun-Mishima correlations developed for narrow channel are better than other correlations. On the other hand, the pressure drop characteristic of flow boiling was analyzed under rolling motion. The two-phase pressure drop changes cyclically due to the rolling motion, rolling angle and period almost have no effect on the fluctuation of pressure drop and the average two-phase frictional pressure drop.关键词
