Experimental Study of Heat Transfer During Acetone and Ethanol Boiling on Horizontal Finned Pipes

Abstract

Experimental study of heat transfer intensity during acetone and ethanol boiling on finned surface at the atmospheric pressure in free movement in the range of heat fluxes of 8-63 kW/m2 has been conducted. The results of boiling of these liquids on cross and longitudinal type finning with various fin geometry have been obtained. The dependencies of temperature head and heat transfer coefficient on a input heat flux have been obtained. Comparative analysis of the effect of the type and the geometry of finned surface has been conducted.
