摘要
A methodology of design and analysis of thermal-hydraulic performance for a single pass 1-1 counter-current flow shell and tube heat exchanger (CCFSTHE) TEMA E-type has been established. The temperature effect on the thermo-physical properties of flowing fluids and on the overall coefficient of heat transfer along the heat exchanger is incorporated in our approach, as well as the coupling between different thermal and hydraulic parameters. It has been noted that the correction factor (F) in the HAUSBRAND formula is not included. Our method brings us to a new dimensionless quantity (MKA) which links the calculation parameters of the heat exchanger to the thermo-physical properties. This dimensionless quantity relates the number of transfer units to the heat flow ratio, R. The results based on our models show a pronounced deviation compared to the model reported in the literature (number of transfer units method). This deviation may be related to a temperature effect not included in the literature model. It has been shown that the results derived from our models are in a good agreement with experimental data. Our new method, named MKA -method, could be a useful tool for theoretical and experimental studies of the design and analysis of the single pass 1-1 CCFSTHE thermal and hydraulic performance for 0 < R <1.
