Studies at the University of Southern California have shown that an unconventional solid-state device, Knudsen compressor, can be operated as a microscale pump or compressor. The critical components compressors are gas transport membranes, which formed from porous materials densely packed parallel arrays channels. An applied temperature gradient across membrane creates thermal creep pumping action. Experimental and computational techniques been developed for investigations will discussed....

With growing public interest in portable electronics such as micro fuel cells, gas total analysis systems, and medical devices, the need for miniaturized air pumps with minimal electrical power consumption is on rise. Thus, development downsizing of next-generation thermal transpiration has been investigated intensively during last decades. Such a system relies mesoporous membrane that generates thermomolecular pressure gradient under action an applied temperature bias. However, highly...
Abstract Finding tangible ways to incorporate inclusion into classroom environments remains a daunting task for many educators. The engineering education literature provides examples of activities try and practices incorporate, but applying the in manner appropriately nuanced an educator's specific situated context takes time effort. There are also unknown factors educators cannot prepare for. In this narrative study, we present story instructor who incremental steps build inclusive...

The Knudsen compressor, based on the temperature gradient driven rarefield flow phenomenon of thermal creep, is a solid-state, micro-mesoscale gas pump or compressor with no moving parts. Experimental studies have shown that compressors can be operated efficiently by either resistive radiant heating techniques, from inlet pressure up to about 10atm down 3×104Pa. A study fundamental limitations encountered in reducing compressor’s operating pressures as low 0.1Pa primary focus present work....

The Knudsen compressor, based on the rarefied flow phenomenon of thermal creep (or transpiration), is an unconventional nano/micro/mesoscale gas pump or compressor with no moving parts. Recent experimental studies single micro/mesoscale stages have indicated that, at low pressures (les 100 Pa), stage performance was decreased in qualitatively somewhat understood and quantitatively not-well-understood ways. investigation reported this paper undertaken to establish a detailed picture thermally...
The Knudsen Compressor is a solid‐state micro/meso‐scale gas roughing pump based on the rarefied phenomena of thermal transpiration. Compressors operate by imposing temperature gradient across high porosity, low conductivity transpiration membrane, typically silicon aerogel membrane. Previous optimization studies have concluded that significant reductions both energy consumption and device volume per unit throughput pressure difference can be achieved when each stage cascade operates with...

Microscale temperature gradient-driven (thermal creep/transpiration) gas flows have attracted significant interest during the past decade. For free molecular and transitional conditions, applying gradients to a flow channel's walls induces thermal creep effect. This results in working flowing through channel from cold hot, which is generally accompanied by rising pressure hot channel. Working distributions can vary significantly, depending on configuration wall distribution. Understanding...
