Helical coils are most widely used enhancement technique because of its compact structure, low cost and long life. The condensation process of steam inside helical coil is investigated for different mass flux range from 68 to 97 Kg/m2s. and different average vapor quality. Experimental data were plotted against flow maps of Breber and Tandon which matches qualitatively. Heat transfer coefficient and overall HTC is plotted against mass flux and average vapour quality which shows it increases with increase in mass flux and vapor quality of steam.
Keywords: Coefficient of heat transfer, Mass flux, vapour quality, flow regime maps.
