摘要

A droplet injection system has been developed for use in a rod bundle heat transfer test facility designed specifically for the study of dispersed flow film boiling during reflood transients in a nuclear reactor. Three different injectors having various pitch configurations and hole patterns were tested. The drop field produced by each was characterized using a laser-assisted size measurement technique. Appropriate mean diameter and drop size distributions that closely simulate the drop field encountered in a reactor bundle assembly under reflood conditions was obtained. The drop injection system developed can readily be employed in the rod bundle test facility to investigate the droplet heat transfer in the dispersed flow film boiling regime.
