Measurements of the Effects of Spacers on the Burnout Conditions for Flow of Boiling Water in a Vertical Annulus and a Vertical 7-Rod Cluster

Abstract

The present report deals with measurements of the effects of spacers on the burnout conditions in a vertical annulus and a vertical 7-rod cluster. The following ranges of variables were studied and 162 burnout measurements were obtained. Pressure p = 31 kg/cm; Inlet sub-cooling 35 < {delta}t{sub sub} < 174 deg C; Surface heat flux 89 < q/A < 305 W/cm{sup 2}; Mass velocity 94 < m'/F < 900 kg/m{sup 2}/s; Burnout steam quality 0.10 < x{sub BO} < 0.56. The experimental results showed that the type of spacers employed during the present investigation had negligible effects on the burnout conditions and that the measured burnout heat fluxes could be predicted within {+-} 5 per cent by means of the correlation by Becker et al for flow in smooth channels.
