In this paper the authors considered compressible isothermal steady subsonic slip
gas flow through microtube at low Reynolds numbers. The dimensions of the
components in microelectromechanical systems (MEMS) are very small (the order of
magnitude is 1 µm), and because of that the effect of gas rarefaction cannot be
neglected, so it should be taken into account. In the analyzed problem gas flow occurs
due to the pressure difference at the inlet and outlet section of the circular microtube,
with the variable cross-section (convergent case, divergent case, case with constant
radius).
The solving approach in the paper is macroscopic, so the fluid flow is defined by the
continuity and Navier-Stokes equations. The rarefaction effect is taken into account by
the velocity slip boundary condition at the walls. The solution process is based on a
perturbation analysis where the order of the terms in the governing equations and
boundary conditions is determined by using the ...exact relation between Mach, Reynolds
and Knudsen numbers. Therefore, with this problem-solving procedure, two
approximations for the pressure and velocity fields are obtained. The first
approximation of the characteristic variables corresponds to the conditions of
continuum flow, while the second approximation shows the effects of rarefied gas flow.
