Determination of Transport Properties for Dilute Gas Mixtures Involving Carbon Tetrafluoride

Abstract

In our previous work, we calculated transport properties of pure gaseous polyatomic carbon tetrafluoride (CF 4) and five equimolar binary gas mixtures of CF 4 with noble gases through inversion technique. The present work is a continuation of our studies on determining the transport properties of binary gas mixtures CF 4 with some gases including three diatomic molecules CO, N 2, and O 2, a linear polyatomic CO 2, and two non-linear polyatomic molecules SF 6 and CH 4. The Chapman-Enskog and Vesovic-Wakeham methods as well as inversion procedure are used to determine the viscosities, diffusivities, and thermal conductivities, which deviates from the literature values within 1%, 4%, and 5%, respectively.
