HEAT TRANSFER BURNOUT OF A SURFACE CONTACTED BY A SPACER RIB

摘要

Measurements showed that the burnout heat flux of surfaces locally insulated by vertical ribs and cooled by downward flowing water was as much as 32％ lower than the burnout heat flux of surfaces without ribs. The results of the tests were correlated by an equation that includes the effects of the thermal conductivity and thickness of the heated surface, the width of the rib tip, and the clearance between the rib tip and the heated surface.
