Extensions to the Navier-Stokes-Fourier Equations for Rarefied Transport: Entropy Variable Formulation, Heat Transfer and Dispersion of a Non-Linear Entropy Stable Closure
Frimpong A. Baidoo, Narayana R. Aluru, Thomas J. R. Hughes +1
We assess the non-linear version of the Entropy Stable Extension to the Navier-Stokes-Fourier equations which were originally derived in arXiv:2407.17334. Using an identity for the…
