FINNED TUBE CONTACT CONDUCTANCE: EMPIRICAL CORRELATION OF THERMAL CONDUCTANCE.

Author(s) : SHEFFIELD J. W., ABU-EBID M., SAUER H. J. Jr

Summary

TESTS WERE CONDUCTED IN A DRY VACUUM ENVIRONMENT, ON MECHANICALLY EXPANDED FINNED TUBE HEAT EXCHANGERS WITH DIFFERENT GEOMETRIES. ONE OF THE EIGHT HEAT EXCHANGERS WAS ALSO TESTED UNDER WET CONDITIONS. A MATHEMATICAL MODEL WAS USED TO CALCULATE THE THERMAL CONTACT CONDUCTANCE FROM THE EXPERIMENTAL DATA. A SCANNING ELECTRON MICROSCOPE WAS USED TO EXAMINE THE CONTACT REGION BETWEEN THE FIN AND THE TUBE. A CORRELATION OF THE DRY CONTACTCONDUCTANCE IN TERMS OF FIN NUMBER, FIN THICKNESS, NET INTERFERENCE, AND UNEXPANDED TUBE DIAMETER WAS OBTAINED.
