The motivation of the current paper is to provide a detailed review of crucial topics in micro-
and nanoscale gas flows, ie, velocity slip and temperature jump phenomena and their …

The Knudsen pump (KP) is a kind of micro-pump that can form thermally induced flows
induced by temperature fields in rarefied gas environments. It has the advantages of having …

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 …

We present an efficient particle simulation method for the Boltzmann transport equation
based on the low-variance deviational simulation Monte Carlo approach to the variable-hard …

Thermal transpiration is the macroscopic movement induced in a rarefied gas by a
temperature gradient. The gas moves from the lower to the higher temperature zone. An …

This paper describes a thermal transpiration-driven multistage Knudsen pump for vacuum
pumping applications. This type of pump relies upon the motion of gas molecules from the …

Measurements of the thermal creep flow through a single rectangular microchannel
connected to two tanks maintained initially at the same pressure, but at different …

We report light-driven levitation of macroscopic polymer films with nanostructured surface as
candidates for long-duration near-space flight. We levitated centimeter-scale disks made of …

Studies at the University of Southern California have shown that an unconventional solid-
state device, the Knudsen compressor, can be operated as a microscale pump or …

In this article, we present the applications of the discrete unified gas kinetic scheme
(DUGKS) for simulating thermal induced non-equilibrium flows. Four different types of …
