Abstract
The Burnett dilute gas second-order theory of the heat flux and pressure tensor is generalized to the rigid polyatomic models, viz., the rough sphere, the loaded sphere, and the spherocylinder. The general Chapman-Enskog method is developed for these rotators. The constitutive equations are expressed in terms of the irreducible tensors associated with gradients of velocity, temperature, and density. Tables and graphs of transport coefficients are presented to show the effect of internal molecular structure. The Wang Chang theory of weak shock waves and the theory of sound wave propagation are extended to dilute polyatomic gases. The transport coefficients for rough spheres and loaded spheres are used to estimate shock thicknesses and damping and velocity propagation coefficients.
