Thermodynamic properties of fluorocarbons: simulations and experiment.
Original language description
We will present our latest research results on the thermodynamic properties of fluorocarbons that are used as unconventional refrigerants within high-tech electronics installations both in particle detectors and in other applications in the electronics industry. The SAFT equations of state were used to model various thermodynamic properties, vapor-liquid phase transition, and equilibrium. Two models were studied and compared in detail: PC-SAFT EoS and Soft-SAFT EoS. Three models were finally implemented in C programming language, since an additional ideal gas model is necessary in order to calculate the ideal gas contributions to the residual thermodynamic properties. A future move towards simulation of binary mixtures is also outlined and studied. A new automated apparatus for speed of sound measurements has been prepared and our own experimental data has been used to verify and evaluate our simulation model results, namely for those regions where no published fluorocarbon experimental data are available. Actual speeds of sound measurements were carried out in two fluorocarbons C3F8 and C2F6 and in a mixture of C3F8 and C2F6. A total of more than 400 new data points along 15 isotherms, with pressures up to 0.5 MPa, were obtained.
