摘要

Abstract

The real gas effect is dominant at high pressure and low temperature

and it is modeled by complex equations of state other than perfect gas law.In the vicinity of liquid-vapor critical point

the real gas exhibits unusual gas dynamic behavior.In the present work

a transient wave fields in unilateral opening pulse tube is simulated by solving the Navier-Stokes equations incorporated with the Peng-Robinson thermodynamic model.The computational fluid dynamics(CFD) results show a remarkable deviation between perfect gas model and real gas model for contact interface and shockwave.The wave diagram based on the real gas model can help to solve the problem of offset design point.
