We discuss physical phenomena in nonequilibrium gas flows where the classical Stokes and Fourier laws for stress and heat transfer are violated. Fundamental differences are revealed between the kinetic description and methods of the thermodynamics of nonequilibrium processes. We study classes of problems for nonequilibrium rarefied gas flows with nonclassical transport. Prospects of experimental verification of the effects are also discussed.
