The thermal conductivity of liquid 1,1,1,2-tetrafluoroethane (HFC 134a)

The dynamic viscosity q and the density p of the ternary mixture heptane (mole fraction .x~) + methylcyclohexane (mole fraction .v2) + I-methylnaphthalene (mole fraction .v3) were measured as a function of temperature T (303.15. 323.15, and 343.15 K) and pressure P (~< 100 MPa). The experimental results correspond to 378 values of q and p. With reference to the 54 values previously published on pure substances and 378 values for the three associated binaries, the system is globally described by 810 experimental values for various values of P, T, and composition.
