review text: Summary: The heat transfer enhancement can be achieved through the secondary flow. It is found that absolute vorticity flux along the main flow can describe the secondary flow intensity and correspond to the heat transfer enhancement averaged in span wise direction. Investigations to verify this phenomenon are reported. The results show that there has a similar distribution for absolute vorticity flux in the main flow direction compared with that for span averaged Nusselt number. The conformance of Nusselt number and absolute vorticity flux shows that absolute vorticity flux can reflect the intensity of heat transfer produced by the secondary flow.
