HEAT TRANSFER CRISIS WITH STEAM-WATER MIXTURES IN COMPLEX GEOMETRIES:EXPERIMENTAL DATA IN ANNULI AND CLUSTERS

摘要

All the heat transfer crisis and pressure drop data for upward flow of steam-water mixtures in test elements having a complex geometry (annuli:360 points;clusters:280 points) obtained under CAN-2 and CAN-3 programs are presented. Tests were performed both without spacers, and with different spacer arrange¬ments.nThis report gives only a short description of results;as the only exception the influence of spacer arrangement is discussed. A complete study of the heat transfer with steam-water mixtures is presented in ref. (13).
