Summary

THE HEAT TRANSFER AND PRESSURE DROP CHARACTERISTICS OF AN ARRAY OF PLATES, ALIGNED AT ANGLES OF 20-35 DEG TO THE DIRECTION OF AIR FLOW IN A RECTANGULAR, STRAIGHT DUCT, HAVE BEEN INVESTIGATED IN THE RANGE OF REYNOLDS NUMBERS BETWEEN 350 AND 5,000. THE HEAT TRANSFER COEFFICIENTS OF THE FORWARD AND BACK SIDES OF THE PLATES HAVE BEEN SEPARATELY DETERMINED, AND THE AVERAGE COEFFICIENT BETWEEN THE TWO CLOSELY APPROXIMATES THE LAMINAR SHORT DUCT THEORY AT LOW REYNOLDS NUMBERS AND IS NEARLY INDEPENDENT OF THE ANGLE OF ALIGNMENT. AT HIGHER REYNOLDS NUMBER THE AVERAGE COEFFICIENT DEVIATES SIGNIFICANTLY FROM THE THEORY. THE PRESSURE DROP MEASUREMENTS THROUGH THE PLATE ARRAY IS A FUNCTION OF THE PLATE ANGLE AND INDEPENDENT OF THE REYNOLDS NUMBER.
