Experimental work was carried out to study the boiling heat transfer from a horizontal 410 ASIS stainless steel cylinder to the pool of binary miscible liquid mixtures at atmospheric and subatmospheric pressures. The mixtures investigated were methanol-water, ethanol-water and isppropanol-watar of varying composition. The heat flux ranged from 9,600 W/m2 to 32,000 W/m2 and the system pressure from 25 33 KN/m2 to 99 KN/m2. It is found that the heat transfer Coefficient varies with the composition of boiling mixture having a minimum value for 30 80 wt. per cent methanol in methanol-water, 31 10 wt. per cent ethanol in ethanol-water and 22 50 wt. per cent isopropanol in isopropanol-water mixtures, respectively. Further, data analysis led to empirical correlations for determining the heat transfer coefficient of a particular composition of alcohol-water mixture.
