Previous research reported various HTC distribution while liquid film cools down the high-temperature wall. Those are not real but the assumption to match the experimental rewetting velocity. In this study, the temperature distribution is taken by using an infrared transparent wall. Finally, the calculated HTC distribution from the result is redefined by the existing formula for pool boiling.
