【 摘 要 】

This paper presents the phenomenon of unsteady Reynolds thermal transpiration flow. The possible constitutive equations in the transpiration shell-like layer were studied analytically and numerically. There has been also examined experimental case of helium flow from cold to hot reservoir in nanopipe.
