Abstract
A set of experiments to research the heat transfer and pressure drop performance of H type fin and tube bundles with in line layouts are conducted. The effects of different geometry parameters including fin width, fin height, fin pitch, transverse tube pitch, longitudinal tube pitch and Reynolds number on heat transfer and pressure drop characteristics are discussed. The correlations of Nusselt number and Euler number deduced by multiple regressions from this paper are well compatible with experimental data, which could provide a theoretical reference of H type finned tubes for industrial applications related to air or gas heat exchangers.
