Heat transfer from an array of strips to fluorinert coolant in a mixed impinging-jet/channel-flow configuration

摘要

Cooling of an array of parallel foil strips stretched on the wall of a narrow rectangular channel to the flow of fluorinert FX3250 is studied experimentally. The coolant is injected in planar jet normal to the center strip, which splits into twostreams to cool the other strips. The data for each strip are correlated in the form of Nu{sub}L/Pr{sup}0.4 as a function of Re{sup}L. The correlations compare favorably to the data of Schafer et al (1991) who conducted experiments using water in similargeometric configurations.
