A three-dimensional numerical study is performed to investigate the heat transfer and pressure drop performance on the air-side of circular finned tube bundles in cross flow. New heat transfer and pressure drop correlations for the air-cooled heat exchangers have been developed with the Reynolds number ranging from 5000 to 70000. The heat transfer and pressure drop results agree well with several existing experimental correlations. In addition, the influence of the geometric parameters on the heat transfer and pressure drop are studied in detail and their results discussed. The numerical flow visualization results for the boundary layer developments, horseshoe vortex system, and local velocity and temperature distributions are presented.
