OPTIMIZATION OF MATRIX HEAT EXCHANGER SURFACESAshish B. Nair DOI: 10.1615/TFEC2017.che.018017 AbstractPerforated plate matrix heat exchangers are mainly used for applications requiring high effectiveness and low volume. This paper attempts to optimize the parameters so as to obtain the best possible configuration for the heat exchanger. The main performance parameters taken into consideration are the Colburn factor (j) and the Fanning friction factor (f). The Colburn factor is related to the heat exchange taking place in the heat exchanger while the friction factor is related to the pressure drop across the heat exchanger. Clearly, the Colburn factor needs to be maximum while the friction factor needs to be minimum. The main objective of this paper is to optimize the heat exchanger conditions to achieve the above j − f relation. |
