The present study illustrates the effects of number of tube rows with vortex generators as well as the arrangement of different vortex generator geometries on local Nusselt number distributions and on friction factors. Trends of local Nusselt numbers and friction factors are provided as they vary with the number of tube row, Reynolds number from 500 to 2000, and the application of vortex generators on the fin surface. It is found that the type and configuration of the vortex generators are the most influential factors on decay of local fin-surface heat transfer enhancement as the number of tube rows increased. Moreover, it is also found that the combination of different vortex generators on the different tube rows could result to better heat transfer performance of the heat exchanger.
