| Abstract: | Experimental investigation on film boiling dispersed two phase friction pressure drop in narrow annular gap with deionized water was performed in three types of narrow annular gap. The friction pressure drop differences were compared between narrow annular gap and circular channel was compared in the paper. The influence of narrow annular gap on friction pressure drop was examined in this paper. Results showed that the modified Sadatomi's correlation can be used to calculate film boiling dispersed two-phase friction pressure drop in narrow annular gap for engineering application. |
