Summary

A REPORT ON THE CONTINUATION OF SYSTEMATIC EXPERIMENTAL STUDIES BEING CARRIED OUT ON THE PROBLEM OF HEAT TRANSFER DURING CONDENSATION ON FINNED HORIZONTAL TUBES, A PROBLEM THAT ARISES FROM THE ESSENTIALLY 3-DIMENSIONED NATURE OF THE CONDENSATE FLOW COMBINED WITH HIGH SURFACE TENSION EFFECTS. WITH FINS OF RECTANGULAR SECTION, THE EFFECT OF FIN SPACING ON THE VAPOUR SIDE HEAT TRANSFER COEFFICIENT WAS OBSERVED FOR R113, ETHYLENE GLYCOL AND STEAM. THE HEAT TRANSFER RATE WAS FOUND FROM THE MASS FLOW RATE AND TEMPERATURE RISE IN THE COOLING WATER AND THE VAPOUR MASS FLOW RATE WAS OBTAINED FROM A STEADY FLOW ENERGY BALANCE BETWEEN THE INLET TO THE BOILER AND THE TEST SECTION. THE NON-CONDENSING GAS CONTENT WAS ESTIMATED FROM THE PRESSURE AND TEMPERATURE IN THE TEST SECTION USING THE IDEAL GAS MIXTURE LAWS AND ASSUMING SATURATION CONDITIONS. ALL TESTS WERE CARRIED OUT AT A VAPOUR VELOCITY OF 0.36 M/S AT THE APPROACH TO THE TEST CONDENSER TUBE. A. H. S.
