Theoretical comparison of two shell-and-tube heat exchangers by applying different correlations

This paper presents the theoretical analysis of heat transfer of two different shell and tube exchangers. The theoretical study was carried out with the creation of software in the EES programming the ɛ-NTU method, considering different correlations for the calculations of the external and internal convective coefficients as well as their geometry for each exchanger, finally performing a mass and energy balance. The theoretical results obtained in this analysis were: operating conditions at the exit of the casing and tubes, efficiencies and total heat transferred in both exchangers, the results obtained were validated with results from other researchers.
