In this research, pool boiling heat transfer coefficient values were experimentally measured up to heat flux 115kW.m-2. Experiments were carried out for pool boiling of pure liquids, including of Formic acid, Propanol, 2-butanol on a horizontal smoothed cylinder, at atmospheric pressure. Applicability of the existing well-known and most common used correlations is comparatively discussed, with the present experimental data. The major predictions (over and/or under) were observed in some parameter range by the existing correlations. In this investigation the correlations of Stephan Abdelsalam, Boyko-Kruzhilin and Mostinski, have been compared with experimental data
