Detailed studies are conducted to investigate the effects of the incident wakes generated by rotating circular cylinders on the characteristics of the transitional boundary layer on the flat plate. In this report, the primary focus is set on the measurement of the time-averaged heat transfer distribution along the flat plate under several conditions of the wake characteristics and the cylinder rotating speed in order to develop simple models in terms of intermittency for the prediction of the transitional behavior of the boundary layer subjected to wakes. Two transition models are employed to be compared with the measured heat transfer data, and then it is found that the geometrical intermittency model which only considers evolution of the turbulent spot in the space-time domain yields better prediction as a whole.
