EXERGY, ENTRANSY, AND ENTRANSY-BASED THERMAL RESISTANCE ANALYSES OF DOUBLE-PIPE HEAT EXCHANGER WITH DIFFERENT PIPE MATERIALS

ABSTRACT

In this research work, exergy destruction analysis, entransy dissipation analysis, and entransy-based thermal resistance analysis are done for a heat exchanger. These analyses are performed with various pipe materials, like steel, cast iron, brass, aluminum, and copper. Various operating parameters are selected for these analyses. The effectiveness of the heat exchanger is also calculated for all conditions. After the analyses, all the results are compared and found those operating conditions at which the performance of the heat exchanger is most excellent. This research can also be used to optimize the design of heat exchangers. With these analyses, correct pipe material and correct operating conditions can be selected. For all these performance analyses, computer soft ware has been developed. This soft ware is helpful for finding all the results without any human error, and it also reduces time consumption for evaluation.
