Abstract
ABSTRACTIn order to establish a reliable procedure for estimation of heat transfer coefficient, experiments on plate finned tube heat exchangers have been conducted on five exchangers. Using own and previously published experimental data databank of 969 working regimes, a new correlation was formed. Correlation is based on hydraulic diameter and porous velocity and on the ratio of characteristic surfaces of the finned tube bundle. Statistical parameters of a new correlation for estimation of heat transfer coefficient are very good, and correlation covers a wide range of geometrical and other parameters of heat exchangers that are industrially important.
