Abstract
Heat transfer rate was evaluated in the heat exchanger that was consists of a heat transfer tube and a condensation tank. Thermal stratification affects the heat transfer rate when steam is injected into a tube through the condensation tank. Thermocouples were installed in the condensation tank to observe the temperature distribution inside. The heat transfer rate was evaluated by temperature distribution in the tank. As a result, the relation between the heat transfer rate due to steam condensation and surrounding cooling water temperature was obtained experimentally, and the behavior of heat transfer with thermal stratification has been revealed.
