EFFECT OF FIN SPACING ON THE PERFORMANCE OF HORIZONTAL INTEGRAL-FIN CONDENSER TUBES.

Type of article: Article

Summary

THIRTEEN TUBES HAVE BEEN USED WITH RECTANGULAR SECTION FINS HAVING THE SAME WIDTH AND HEIGHT (0.5 AND 1.6 MM) AND WITH FIN PITCH VARYING FROM 1.0 TO 20. 5 MM. TESTS WERE MADE USING A PLAIN TUBE HAVING THE SAME INSIDE DIAMETER AND AN OUTSIDE DIAMETER EQUAL TO THAT AT THE ROOT OF THE FINS. THE HEAT TRANSFER ENHANCEMENT FOR THE FINNED TUBES SIGNIFICANTLY EXCEEDED THAT TO BE EXPECTED ON GROUNDS OF INCREASED AREA. PLOTS OF ENHANCEMENT AGAINST FIN DENSITY WERE REPEATABLE AND SHOWED LOCAL MAXIMA AND MINIMA. THE DEPENDENCE OF ENHANCEMENT ON FIN DENSITY DID NOT DEPEND APPRECIABLY ON VAPOUR VELOCITY OR CONDENSATION RATE FOR THE RANGES USED.
