gas mixtures. The calculations for each method established the
insignificant differences between them. The impact of the mixture temperature on its vis-
cosity is significantly more important than choosing the method which affects the result
in the considered range of concentrations.
Keywords:
viscosity, working fluid, high-temperature turbine, gas mixture, determination
of properties.
