ANALYTICAL SOLUTION OF THE NONHOMOGENEOUS KINETIC EQUATION IN THE PROBLEM OF ISOTHERMAL SLIP OF A RAREFIED GAS ALONG A SOLID SPHERICAL SURFACE
V. N. Popov UDC 533.72 An analytical method of solution of a half-space boundary-value problem for the nonhomogeneous kinetic Boltzmann equation with a collision operator in the form of an ellipsoidal-statistic model in the problem of isothermal slip of a rarefied-gas flow along a solid spherical surface is presented. Within the framework of the considered model, a correction to the coefficient of isothermal slip that is due to the wall curvature is obtained. Comparison with literature data is made.
