Experimental Investigation on Heat Transfer Characteristic of Saturated Boiling in Round Tube

An experiment on saturated heat transfer characteristic in round channel was carried on using water. The dimension of round tube isφ9.5 mm×1 mm with a 1000 mm heating length. The dimensionless Re_lo number and Bo number were used as important parameters to predict heat transfer coefficient in round channel. Based on the two dimensionless numbers, the data were used to develop a new correlation. The correlation was then tested against the experimental data, the error was about ±20%.
