The heat exchanger has been divided into three equal sections in order to allow examination of the intermediate stream temperature conditions and temperature distribution through the heat exchanger. Water to Water Turbulent Flow Heat Exchanger is a highly advanced concentric tube heat exchanger with hot water flowing through the central tube while cooling water flows through the annular space. The addition of the central tube surface temperatures at inlet and exit allow detailed investigation of the surface heat transfer coefficient inside and outside the central tube. Thermocouples sense the hot and cold stream temperatures at the four stations and the inner tube wall temperatures on entry and exit.
