Title:The Mesoscopic Peristaltic Compressor
Author(s):Sulfridge, M.A.; Miller, N.R.
Subject(s):mesoscopic compressors
peristaltic action
Abstract:A new design for a meso-scale (miniature) compressor has been developed and analyzed. The tenn meso is used to describe a device which is smaller than a traditional (i.e. macro) device, and yet larger than the micro devices which have been developed in recent years. This scale of compressor is essential for the development of air conditioning systems small enough to be easily portable and efficient enough to require relatively low power to operate, while still being large enough to do appreciable work. The design under investigation is based on peristaltic action, in which controlled waves are used in rapid succession to propel a fluid down a continuously tapering channel. Electrostatic actuation is used to control the wave. A detailed analysis of this design is performed from an energy standpoint, and many of the major differences between this type of compressor and comparable traditional compressors are highlighted. In addition to the detailed energy analysis, some simple dynamic modeling has also been performed to address transient effects such as squeeze-film damping.
