The authors are aiming at controlling actively the heat transfer performance in low Reynolds number flow with photo-rheological fluids (PRFs) whose rheological properties can be tuned by UV irradiation. We examine the flow structures of UV-irradiated and non-irradiated PRFs in a serpentine channel by PIV, and investigate the correlation between the flow behaviors and the heat transfer rate. As a result of the experiment, UV-irradiated PRF flow becomes almost symmetric to the center of the channel and steady, while non-irradiated PRF flow has flow distortion and unsteadiness. This may lead to change the heat transfer characteristics.
