Time-dependent Regularized 13-Moment Equations with Onsager Boundary Conditions in the Linear Regime
Bo Lin, Haoxuan Wang, Siyao Yang +1
We develop the time-dependent regularized 13-moment equations for general elastic collision models under the linear regime. Detailed derivation shows the proposed equations have su…
