Abstract: The modified Taxman transport coefficient formulae have been obtained correctly up to the first approximation for a pure hard-ellipsoidal low-density fluid in terms of four-dimensional quadratures over the coordinates of two interacting ellipsoidal molecules. In the appropriate limits, these expressions reduce to the corresponding transport coefficient formulae for a spheroidal or a hard sphere (HS) system. The HS formula for the thermal conductivity agrees with the modified Eucken formula to the first approximation implying that the basic ingredients of the latter formula are embedded in our formulation. The various quadratures have been computed for the ellipsoidal as well as spheroidal systems. The numerical results for the transport coefficient are presented in the form of universal curves for each kind of model fluid as functions of axial ratios of the molecules. It has been found that our thermal conductivity work is superior to that of Mason and Monchick.
