| Abstract: | Based on the intercooler used for 280 diesel engine of locomotive,the heat transfer characteristics of finned circle tube bank heat exchanger surface with punched vortex generators are experimentally studied by condensing method with different fin spacing.The comparison of results obtained by condensing method and naphthalene sublimation method is given.The results show that the difference of results obtained by both methods is small. |
