Many small-scale energy systems require effective miniaturized pumps and expanders. These devices are responsible for conveying a working fluid through various components to execute a cycle that may result in power production, heat pumping, or refrigeration. As an example, a pump is required for pressurizing the working fluid in Rankine power cycles. Miniaturized pumps could also cycle a heat transfer fluid through a cooling loop for heat rejection purposes. On the other hand, expanders are necessary for any cycle employing a working fluid to generate power. Specific examples include microturbines, miniaturized piston-based machines, and roots-type expanders. (more…)
