Summary

HEAT TRANSFER FROM AN ARRAY OF PARALLEL LONGITUDINAL FINS TO A TURBULENT AIR STREAM PASSING THROUGH THE INTERFIN SPACES HAS BEEN INVESTIGATED BOTH ANALYTICALLY/NUMERICALLY AND EXPERIMENTALLY. IN THE ANALYTICAL/NUMERICAL WORK, A CONJUGATE PROBLEM WAS SOLVED WHICH ENCOMPASSED TURBULENT FLOW AND HEAT TRANSFER IN THE AIR STREAM AND HEAT CONDUCTION IN THE FINS AND IN THE BASE PLATE. THE LOCAL HEAT TRANSFER COEFFICIENTS VARIED ALONG THE FINS AND THE SURFACE OF THE BASE PLATE. THE NUMERICALLY DETERMINED FIN EFFICIENCIES DID NOT DIFFER APPRECIABLY FROM THOSE CALCULATED FROM THE CONVENTIONAL PURE-CONDUCTION FIN MODEL.
