The theory which forms the basis for discussions of the transport phenomena in dense gases is Enskog s kinetic theory for a pure gas made up of rigid spheres (E3, C3, Chapter 16 Hll, 9.3). To date, this theory in one of several modifications is the best theory available for calculating the temperature and density dependence of the transport coefficients. Recently Enskog s theory has been extended to a pure gas made up of nonrigid molecules by Curtiss and Snider (CIO, C14). Enskog s theory has also been extended to binary gas mixtures by Thorne (C3, p. 292).
