- Abstract
- Positive displacement machines have acquired particular popularity with the current push for sustainable energy production and consumption. It is currently not acceptable to waste energy available in high-pressure gasses throttled or vented to atmosphere in industrial processes (Samuel, 2007; Shu, Yu, Tian, Wei, & Liang, 2014) or blown out of cylinders in large diesel engines (Amann, 1987; Panesar, 2015; Karvountzis-Kontakiotis, Pesiridis, Zhao, Alshammari, et al., 2017). For such applications, a suitably sized positive displacement machine would be employed to harvest energy from these gases and transform it into useful forms. Turbines that are traditionally employed in massive power plants cannot be used for energy harvesting applications due to their inability to handle neither two-phase vapors (Groniewsky, Gy€orke, & Imre, 2017) nor flow occurring at small rates. For these applications, a gas expander, which is a positive displacement machine is usually employed. In relation to pressure creation, positive displacement pumps and compressors are commonly employed to impart pressure to respectively gaseous and liquid fluids flowing at rates which are required by most industries. This chapter presents the limac¸on rotary positive displacement machine, which can be employed for energy production (i.e., as a gas expander) and energy consumption (i.e., as a compressor or a pump) with equal ease and effectiveness. The limac¸on machine (Sultan, 2005) offers a straightforward technology, which has occurred to many creative minds as evident by patents which can be traced back to the 19th century. However, it is unfortunate that such technology did not make it to mass production due to the lack of mathematical understanding of their geometric characteristics and unavailability of manufacturing tools required to machine their chambers. Recently, however, with technical papers published on the topic, industry take-up of the technology has started to emerge. A good example of this take up is shown by the patent of Nystrom (2016).
