The various calculating methods currently used for viscosity and thermal conductivity of the gas mixture with condensable components in inter_cooler of turbine compressor were compared with experimental results. The proper and effective methods and the mixed laws on calculating viscosity and thermal conductivity of the gas mixture were established after the relations were selected and fitted with experiments. Then the viscosity and thermal conductivity of the gas mixture with condensable components were calculated by using the methods and mixed laws on the basis of phase equilibrium. The results of calculation show that the calculation method and the mixed law were more effective and reasonable.
