Abstract:

By using Prandtls boundary-layer theory, equations are derived for a moderately rarefied gas which differ from the ordinary Prandtl equations by the presence of supplementary terms that contain higher derivatives of velocity and temperature in the equations derived, the normal pressure gradient differs from zero and is expressed by supplementary terms. The boundary conditions for these equations are found with the aid of kinetic theory they are a generalization of Maxwells and Smoluchowskis conditions for motion at a supersonic velocity. The velocity and height limits of applicability of the equations derived are set forth. Author
