  Analysis of Porous Media Tube Cooling in a Rankine Cycle SCO2 Heat Exchanger

  By Kevin R. Anderson, Thomas J. Gross, Christopher McNamara

  Abstract: This paper presents analysis of a supercritical CO2 (SCO2) shell and tube heat exchanger for use in a waste-energy recovery Rankine cycle. Heat transfer augmentation through the use of porous media to cool the tube side of the heat exchanger is presented. The variability of the specific heat of SCO2 at high side (shell side) pressure 20 MPa and low side pressure (tube side) of 12.4 MPa is presented. Second …
