It is well known that in a gas-filled duct or channel along which a temperature gradient is applied, a thermal creep flow is created. The performance of a new type of Knudsen pump, which only requires

isothermal hot ...

A rarefied gas is considered in a channel consisting of two infinite parallel plates between which

an evenly spaced array of smaller plates is arranged normal to the channel direction. Each of

these smaller ...

A net gas flow can be induced in the gap between periodically structured surfaces held at fixed

but different temperatures when the reflection symmetry along the channel axis is broken. Such a

situation arises ...

Rarefied gas flows in nano-scale isosceles triangular cavities with a motion away from the square corner are considered over a wide range of flow rarefactions regimes, i.e., 0.01≤Kn≤10, using the direct simulation Monte ...

We present a detailed description of the characteristics of a ratchet-type small-scale gas-pump suggested by Donkov et al. [1]. The pump consists of a ratchet channel with the temperature gradient applied between the ...

Here, flow in the gap between periodically structured surfaces is studied when the reflection symmetry along the channel axis is broken. A series of triangular fins with alternating specular and diffuse walls are placed ...

Utilization of thermally driven flows in the gap between periodically structured surfaces has been

studied in the previous works. Donkov et al. [1] considered a ratchet channel with the temperature

gradient ...

It is well known that in a gas-filled duct or channel along which a temperature gradient is applied, a thermal creep flow is created. Thermal creep flow has attracted the attention of many researchers. For example Akhlaghi ...

Knudsen pumps transport gas by imposing a temperature profile onto a rarefied gas confined within a

channel with structured walls. We investigate the influence of specularly reflecting wall segments on the

pumping ...
