Investigation on the optimum performance of a class of irreversible three-source chemical pumps

Abstract

根据驱动能流的不同,人们将热力学机分为热机、化学机和其它类型机。对于热流驱动的热力循环设备已经有了大量的研究,特别是有限时间热力学的应用,使这一领域的研究更加活跃。近十几年来,应用有限时间热力学方法研究热力循环已经拓展到化学反应、化学机和化学泵等循环设备。类似于可由太阳能,地热能,工业废热等热流驱动的三热源热泵,三源化学泵是以质量流而不是以高品位的功来驱动循环的新型化学循环系统,它工作在三个化学势不同的物质库(称之为驱动库、泵质库和环境库)之间,应用这类循环设备对于节约能源和减少环境污染等具有重要意义,符合可持续发展的战略目标。本文建立受传质不可逆性、工质内部不可逆性和质量漏等多种不可逆因素影...According to the difference of energy currents which are used to operate the engines, it is possible to distinguish thermodynamic engines into thermal, chemical and other engines. A lot of the research work has been done in thermodynamic cycle devices driven by heat currents. Especially, the application of the finite time thermodynamics has made the investigation in this field more active. In rece...学位:理学硕士院系专业:物理与机电工程学院物理学系_理论物理学号:20012400
