Description
Summary:A new formulation of the inner boundary problem for description complex nonequilibrium flows between membranes is presented. Solutions by means of the Boltzmann equation and the model kinetic equation for mixtures with chemical reactions demonstrate interesting physical properties in this open nonequilibrium system. Possibility of the anomalous thermal transport where the heat flux and the temperature gradient are of the same sign, is studied. Influence of boundary conditions on the parameters of the structure is considered as well.
