IN THE PROBLEM OF ISOTHERMAL SLIP OF A RAREFIED GAS 
ALONG A SOLID SPHERICAL SURFACE

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.
