Derivation of Grad's Thirteen Regularized Moment Equations Using a Hermite Polynomial Representation of Velocity Distribution Function (Preprint)
Abstract
This paper derives the transport equations for rarefied gases from the Bhatnagar-Gross-Krook (BGK) model kinetic equation using Hermite polynomial representation of the velocity distribution function. We apply the Champmen-Enskog method to Grad's thirteen moment equations to derive a closure of Grad's 13 moment equations, extending them to third order of the Knudsen number. The velocity distribution function for the resulting 13 regularized moment equations is presented.
