The flow rate of water through carbon nanotube (CNT) membranes is considerably large. Hence, CNT membranes can be used in nanofluidic applications. In this work, we performed a molecular dynamics (MD) simulation of the introduction of water into CNTs in the CNT membranes, especially in vertically aligned CNT forests. The results showed that the Knudsen number (Kn) increased with an increasing v...

The paper presents an analytical solution for the non-isothermal compressible gas flow in a slide microbearing with different temperatures of walls. is defined by Navier-Stokes-Fourier system continuum equations and first order boundary conditions. Knudsen number corresponds to slip (Kn ≤ 10 −1 ) Reynolds moderately high, so inertia needs be included. obtained perturbations approximation that r...

Hypersonic rarefied-gas flows near two side-byside cylinders have been studied numerically with the direct simulation Monte-Carlo technique under transitional rarefied-gas-flow conditions (Knudsen numbers from 0.0167 to 10). Strong influences of the geometrical factor (ratio of distance between cylinders to cylinder diameter) and the Knudsen number on the flow structure (the shape of shock wave...

For gas flows in microchannels, slip motion at the solid surface can occur even if the Mach number is negligibly small. Since the Knudsen number of the gas flow in a long microchannel can vary widely and the Navier-Stokes equations are not valid for Knudsen numbers beyond 0.1, an alternative method that can be applicable to continuum, slip and transition flow regimes is highly desirable. The la...
