摘 要:A steady plane subsonic compressible non-isothermal Couette gas flow is analyzed for moderately high and low Reynolds *** flow channel is formed by two plates in relative *** cases are considered:(a) isothermal walls where the temperatures of the plates are equal and constant and(b) with constant but different plate *** Knudsen number is Kn 0.1,which corresponds to the slip and continuum *** flow is defined by continuity,Navier-Stokes and energy continuum equations,along with the velocity slip and the temperature jump first order boundary *** analytical solution for velocity and temperature is obtained by developing a perturbation *** first approximation corresponds to the continuum flow conditions,while the others represent the contribution of the rarefaction *** addition,a numerical solution of the problems is given to confirm the accuracy of the analytical *** exact analytical solution,for constant viscosity and conductivity is found for the isothermal walls case as *** is shown that it is entirely a substitution to the exact numerical solution for the isothermal walls case.
