Abstract : Thermal and hydraulic performance of printed circuit heat exchanger (PCHE) has been evaluated using numerical
methods. Also, performance at various fin configurations has been compared with the original configuration[1]. For the
numerical simulation, a commercial code ANSYS-CFX has been adopted along with ANSYS-ICEM CFD for structured
mesh generation. Temperature and pressure conditions on the cold side of PCHE fall near the critical point of where
thermophysical properties of vary sharply with changing conditions of temperature and pressure. For accurate
performance prediction of PCHE, provision of precise thermophysical properties of the working fluid is mandatory. In the
current study thermophysical properties of were supplied to solver through real gas property (RGP) table. An in-house
Matalb code was used to write the high resolution RGP files by coupling the Matlab program with the NIST’s REFPROP.
