摘要:
There are two effects giving rise to density corrections to the dilute gas transport coefficients. These are, (a) the corrections to the binary collisions due to their finite size and time of duration and (b) the triple collision effect. Neglecting the latter, expressions for the transport coefficients are well known and have been evaluated in the case of rigid spheres. These expressions for the transport coefficients are now simplified and evaluated approximately for inverse power potentials. The approximation consists in an expansion in inverse powers of the repulsion exponent a technique which has been shown by Baroody to give good agreement with exact calculations of the &OHgr; integrals.
