摘要

LMMHD能源转换(EC)系统的研究和开发始于20世纪60年代,已经走过了漫长的道路,正在走向商业化。这种系统的设计和开发必须处理与熔融金属的单相和两相流动有关的许多问题,包括两相流动的不同模式、相间、现象、传热、LMMHD组件的性能以及液态金属与其他流体和约束材料的相容性。多年前提出的液态金属MHD (LMMHD)电力转换系统在其各种提出的模式中越来越受到关注,包括单相或两相流体流动,用于广泛的热源,例如太阳能,废热,核能等。液态金属MHD (LMMHD)电力系统最近被提出用于低品位热源的直接电能转换,如太阳能。太阳能LMMHD发电系统在效率和单位装机成本方面非常有吸引力。介绍了在这些系统的各个方面进行的理论和实验研究。本文描述了迄今为止在太阳能LMMHD电力系统领域所进行的活动的最新情况。

Solar-assisted liquid metal MHD power generation: A state of the art study

The research and development of LMMHD energy conversion (EC) systems which started in the 1960s has already come a long way and is heading towards commercialization. Design and development of such systems has to deal with a number of questions relating to single- and two-phase flows of molten metals, including different patterns of two-phase flow, interphase, phenomena, heat transfer, performance of LMMHD components and compatibility of liquid metals with other fluids and with confinement materials. Liquid metal MHD (LMMHD) power conversion systems proposed many years ago are gaining increasing attention in their various proposed modes, consisting of single-phase or two-phase fluid flow for a wide range of heat sources, e.g. solar energy, waste heat, nuclear energy, etc.

Liquid metal MHD (LMMHD) power systems have been recently proposed for direct electrical energy conversion of low grade thermal sources of energy, like solar energy. Solar-powered LMMHD power generation systems are very attractive regarding efficiency and cost per unit of installed power. Theoretical and experimental investigations carried out in the various aspects of these systems are presented. A state of the art review of activities in the solar-powered LMMHD power systems field which have taken place so far is described here.
