Detailed studies are again conducted to investigate the characteristics of the transitional boundary layer on the flat plate which is subjected to wakes generated by rotating circular cylinders with diameters larger than those in the 1st report. In this paper, the 2nd report, the focus is on the modification of the previously proposed model of the intermittency factor of the transitional boundary layer influenced by the wakes. It is consequently found that the newly developed model, taking account of the effect of wake duration, yields better predictions of the time-averaged heat transfer for the wide range of wake conditions covered in this study. Furthermore, it is confirmed that the forced transition may begin near the instability point of the laminar boundary layer.
