Summary

PER-TUBE HEAT TRANSFER COEFFICIENTS WERE DETERMINED IN A TUBE BANK IN THE PRESENCE OF AN ABRUPT UPSTREAM ENLARGEMENT OF THE FLOW CROSS SECTION. THE ENLARGEMENT OCCURRED EITHER AT THE INLET FACE OF THE TUBE BANK OR AT THE UPSTREAM END OF A DUCT WHICH DELIVERED THE FLOW TO THE INLET. THREE DIFFERENT MAGNITUDES OF ENLARGEMENT WERE INVESTIGATED ALONG WITH THREE LENGTHS OF THE DELIVERY DUCT. IT WAS FOUND THAT THE ENLARGEMENT CAN GIVE RISE TO APPRECIABLE INCREASES IN THE TUBE BANK HEAT TRANSFER COEFFICIENTS COMPARED WITH THOSE FOR THE NO-ENLARGEMENT CASE AND CAUSES AN ADDITIONAL PRESSURE DROP WHICH DEPENDS ON THE MAGNITUDE OF THE ENLARGEMENT AND, TO A LESSER EXTENT, ON THE DISTANCE BETWEEN THE ENLARGEMENT AND THE TUBE BANK.
