Abstract
This article deals with the problem of temperature jump and slip velocity at the wall in gas/surface interaction. A consistent modelling of an impermeable surface involving an anisotropic scattering kernel developed in previous works is used to establish boundary conditions in unstructured molecule gas ﬂows. Thus a temperature jump relation is derived in which the gas viscous eﬀects at the wall and the mean velocity gradients appear. Likewise, a slip velocity relation is obtained in which both the slip coeﬃcient and the thermal creep coeﬃcient depend on the walltogas temperature ratio. Moreover, both the temperature jump and the slip velocity relations involve not only one accommodation coeﬃcient as in usual expressions, but also the gas/surface information through the various (notably normal and tangential) accommodation coeﬃcients of the momentum components.
