Hodges, M W

In early 1971, burnout results with a surface contacted by a rib were correlated as a function of rib thickness, heater thickness, and thermal conductivity. The correlation was thought to include the effects of velocity decrease and heat flux increase near the rib. An analytical analysis was used to apply these results to a heater cooled from two surfaces. A re-analysis of these results indicated that the rib nonideality factor is a function of subcooling. An experimental program was initiated to define the burnout heat flux with rib contact for all coolant conditions of interest in SRP reactors. This memorandum presents a burnout heat flux correlation for a surface contacted by a rib and compares the predicted burnout heat fluxes with previous predictions. 6 refs., 13 figs., 2 tabs.
