| Abstract: | The method of thermodynamics analysis is employed to investigate on the thermal performance of regenerative heat exchanger.The exergy efficiency is introduced to combine heat transfer and fluid flow characteristic.It is shown that the exergy efficiency is more efficient in expressing the thermal performance of heat exchanger than the thermal efficiency and temperature efficiency.This index can be used for the optimal design of regenerative heat exchanger. |
