Abstract:

 It has recently been recognized that a large quantity of waste heat is generated annually, and thus represents a large opportunity for energy savings. With burgeoning research in cycles which utilize super critical carbon dioxide as a unique organic working fluid. This paper focuses on the analysis of a heat exchanger for use in conjunction with a Supercritical CO2 (SCO2) Rankine low grade waste-heat energy recovery cycle. The NTU- method is used to design the heat exchanger. Porous media flow is used for heat transfer augmentation on the tube side of the heat exchanger. Second law analysis has been used to place a practical limitation on the results of pinch point versus heat exchanger area published in this study.

Keywords:

Supercritical CO2, Heat Exchanger, Exergy, Renewable Energy, Porous Media Flow.
