The knowledge of two-temperature transport coefficients over wide temperature and pressure range is essential to model the flow and heat transfer in plasma process. In this study, the plasma composition is calculated using the Saha equation and the transport coefficients are worked out using Chapman-Enskog method expanded up to higher approximation. The electron temperature Te is assumed to be different from that of heavy species Th. The evolutions of viscosity, thermal conductivity, and electric conductivity of helium plasma are presented in elctron temperature range from 300 K to 40 000 K. It is shown that the transport coefficients strongly depend on pressure and non-equilibrium parameter (θ= Te/Th). These values in local thermodynamic equilibrium state accord well with previously reported data.
