Does the Chapman–Enskog expansion for viscous granular flows converge?


This paper deals with the convergence/divergence issue of the Chapman–Enskog series expansion of the shear and normal stresses for a granular gas of inelastic hard spheres. From the exact solution of a simple kinetic model in the uniform shear and longitudinal flows, it is shown that (except in the elastic limit) both series converge and their respective… (More)
