Cold gas propulsion systems are mainly used for attitude controlof satellites.It is possible to obtainvery low pressure and temperature at the exit section of the nozzledue to propulsion system’s nature. Investigation of steady state performance of a cold gas thruster under real gas effects is decided to be carried out. SU2, an open source compressible CFD tool,is used for analyses ofideal gas, Peng-Robinson and van-der Waals gas models. Vacuum chamber test facility of Roketsan is usedfor performance tests. Results showed that van der Waals gas model in SU2is good enough for predictions of cold gas thruster’s performance.
