“…Analysis of heat and fluid flow in various-shaped microchannels has been studied extensively in the past decades [4][5][6][7][8][9][10], to name a few. However, theoretical research on slip flow in porous-saturated microducts of arbitrary cross-section has not been conducted to the same extent.…”

“…On the other hand, temperature jump relations are generally derived using either a complete diffuse scattering kernel [7,13,14] or at best using only one accommodation coefficient in the surface modelling [8,9,[15][16][17]. A very similar way is generally used to obtain the slip velocity [2,18,19]. However it is well known that the completely diffuse scattering kernel is not a good surface description [20].…”

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 wall-to-gas 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
