【Abstract】 A simple method based oh the heat resistance method has been presented to solve the solidification problems. This paper calculated the heat exchanger effectiveness of phase change heat exchanger. The comparison between nunerical and exoerimental results shows that the new method can satisfy the engineering need well. Finally, the paper discussed the heat transfer properties of Concentric Circular Tube phase change heat exchanger.更多还原
