The time and spatial temperature variations and smoke flow behaviors were simultaneously measured by using an infrared radiometer and a video camera in order to obtain the information about heat transfer characteristics downstream of vortex generator. The vortex generator, a thin rectangular plate, was set in the bottom of the two dimensional duct with 20 degrees inclined oncoming flow. It was found that the vortices were periodically generated downstream from the vortex generator and the temperature field well corresponds to the location of the vortices. Moreover this method will be useful for understanding the heat transport phenomenon.
