Summary

A HIGHLY EFFECTIVE METHOD FOR HEAT TRANSFERENHANCEMENT IN TUBE AND PLATE-FINNED HEAT EXCHANGERS THROUGH ARTIFICIAL FLOW TURBULIZATION IS PROPOSED. A CORRELATION FOR THE INCREASE IN HEAT TRANSFER IS FOUND AS A FUNCTION OF INCREASING HYDRAULIC RESISTANCE FOR CHANNELS OF VARIOUS CROSS SECTIONS. RESULTS ARE COMPARED WITH SIMILAR SMOOTH CHANNELS WITH DISCRETE WALL FLOW TURBULIZATION. THE USE OF THE PROPOSED SURFACES ALLOWS A 1.5 TO 2 FOLD DECREASE IN THE HEAT EXCHANGER VOLUME, A 3 TO 8 FOLD INCREASE IN FILM BOILING HEAT TRANSFER, A 1.4 FOLD INCREASE IN SURFACE BOILING HEAT TRANSFER, AND A 2 TO 3.4 FOLD INCREASE IN CONDENSATION HEAT TRANSFER ON THE OUTER SURFACES OF ANNULAR GROOVED TUBES.
