Open publisher page 0 citations

Abstract

CO_2-air heat exchanger was studied and tested and the heat exchanger's performance curve,relationship of factor j and f,reynolds number and the flow field distribution were got. Results show that the pressure drop is 5%～10% lower in cooling model than no heat exchange,and there is no much change about factor j and f despite of the heat transfer condition.When compared with the reference datum,the measured factor f coincides with it very well,and factor j is slightly lower than it.
