Abstract : A modified form of the Chapman and Enskog transport theory for gas mixtures was developed for a neutral, binary mixture with disparate molecular weights. The difficulties in the past have been that the usual Chapman and Enskog theory was based on a single time scale for the molecular relaxation. As pointed out by Grad, this relaxation occurs on a multiple time scale, and this fact is exploited in deriving a modified Chapman and Enskog theory. (Author)
