Foundations of Multimoment Hydrodynamics. Part 1: Ideas, Methods and Equations

The Boltzmann hypothesis of molecular chaos (“Stosszahlansatz”) closes the classic kinetic equation. Equations of classic hydrodynamics that directly follow from the Boltzmann equation inevitably contain the error involved in the derivation of classic kinetic equation. The physical meaning of the error introduced by the Boltzmann hypothesis in the equations of hydrodynamics is as follows. Only the...
