摘      要：Correlations are crucial to the design of cooling channels employed in regenerative cooling systems for *** this paper,correlations for the aviation kerosene flowing upward and downward in vertical tubes are studied and *** existing correlations are assessed against the available experimental *** further improve the prediction accuracy of the heat transfer behaviors of the supercritical aviation kerosene,a new dimensionless parameter(Qi)relevant to the heat flux is proposed and introduced into the construction of a new *** shows that the new correlation is more accurate than existing correlations.
