Prediction of thermodynamic properties of gas mixtures using the Peng-Robinson equation of state

This bachelor thesis summarizes basic thermodynamic concepts necessary for calculation of speed of sound in mixtures of real gases using the Peng Robinson equation of state. Moreover, two different group contribution methods are used to estimate thermodynamic properties of refrigerants C2F6 and C3F8. The analytical prediction of speed of sound in mixtures of N2 and C3F8 is then confronted with experimental data measured on sunar tube gas analyzer. Finally, the accuracy, sources of error and overall potential of this approach is discussed.
