Non-existence of the global solution of initial boundary value problem for the incompressible two-velocity medium equation

An initial boundary value problem for systems of viscous two-fluid media with equilibrium of pressure phases is considered. Using the test function method proposed by S.I. Pohozhaev and E. Mitidieri, the effect of boundary and initial conditions on the appearance, time and rate of destruction of solutions of this problem...

A comparative analysis of kinetically consistent schemes with several grid methods for solving gas-dynamics problems

The equations of gas dynamics are an integral part of numerical models of the atmospheric dynamics used for research into variations of climate and anthropogenic changes in the environment. Various modifications of the discrete kinetic models describing a single-particle distribution function are reviewed and tested. A comparison of test solutions...
