Abstract
An analysis of the Hagen-Poiseuille flow for a rarefied gas is presented using Grad’s equations and regularized equations in the 13 moment approximation, which provide a correction for the solution in the hydrodynamic regime. Slip boundary conditions are obtained through a simple wall model in which we take into account diffuse and specular wall-particle interactions. From the solution of the regularized equations, we recover as a special case, the velocity profile in Grad’s approximation and also an equivalent expression in the hydrodynamic regime. In addition, other relevant variables are calculated.
