ABSTRACT = {In this study, the thermal-hydraulic performance of eight different printed circuit heat exchanger (PCHE) configurations with supercritical liquefied 
natural gas as the working fluid are studied by a numerical method. Firstly, the thermal-hydraulic performance of the PCHE with different airfoil fins 
are investigated at different operating pressures, which indicate that the PCHE with airfoil fins has better thermal performance but worse hydraulic
performance when it operates at higher pressure condition. Furthermore, the effects of different airfoil configurations on the thermal-hydraulic 
performance are analyzed in detail. The results show that asymmetric airfoils can provide better heat transfer performance than symmetrical airfoils.
Finally, the overall heat transfer performance of PCHEs is evaluated by the identical mass flow rate criterion, identical pressure drop criterion and 
identical pumping power criterion, respectively. The results show that NACA 0024, NACA m18 and NACA 23021 airfoil fins exhibit the best 
comprehensive performance, respectively.},
