Macroscopic Relations in Rarefied Shear Flows

Abstract

The plane Couette flow and hypersonic flow past a flat plate at a zero angle of attack are investigated. The relations between stresses and heat fluxes in the Couette flows and the gradients of velocity and temperature are derived. These relations are the generalization of Newton-Fourier (Navier-Stokes) relations for the shear flow with strong nonequilibrium. The relation between longitudinal heat flux, on the one hand, and both transverse heat flux and shear stress with another, is detected. The possibility of application of the relations, derived for Couette flow, to hypersonic flow past flat plate at zero angle of attack is investigated. The limits of applicability of Burnett relations for this flow are determined
