Type of article: Article


An analytical investigation of heat transfer in a counterflow spiral plate heat exchanger is the subject of the study. A new dimensionless criterion number is proposed. For any heat capacity rate ratio and for an arbitrary (even) number of turns one uniform, universal and simple formula is developed to calculate the mean temperature difference correction factor of a spiral plate heat exchanger. The accuracy of the theory increases with the growing number of channels.
