Abstract

In this paper, we introduce a novel technique to measure the unsteady feature of turbulent heat transfer using high-speed infrared thermograph. High-speed imaging is necessary to capture the unsteady feature since the turbulent heat transfer is originated from the turbulent vortical structure which fluctuates in high speed and in complicated manners. The experimental technique was introduced here to measure the turbulent heat transfer, and presented an example of quantitative variation of spatio-temporal heat transfer, which has not been clarified experimentally so far. In addition, the requirement to the infrared thermograph to capture the sufficient fine structure was discussed.
