Three-dimensional complex turbulent flow and heat transfer of internally longitudinally finned tube with blocked core tube and streamwise wavy fin are numerically investigated. The numerical method is validated by comparing the calculated results with corresponding experimental data. The effects of both wave height and wave distance on heat transfer performance are examined. The range of wave height to hydraulic diameter ratio is from 0.61 to 2.45, and that of wave distance to hydraulic diameter ratio is from 3.06 to 14.69, while that of Reynolds number is from 904 to 4520. The computational results demonstrate that the Nusselt number and friction factor increase with the increase of the wave height, while they decrease with the increase of the wave distance. Furthermore, general correlations are proposed to describe the performance of the wavy configuration for , , , with the mean deviations for heat transfer and friction factor correlations being and , respectively.
