摘要
浆态是一种固态与液态物质共存的状态,即在液体中含有固体小颗粒。浆氢在用作火箭和航天飞机的燃料方面有很广泛的应用前景;采用浆氮作为高温超导电缆的制冷剂则会明显提高电缆的冷却性能。主要介绍了浆氢和浆氮的制备方法,密度和流量的测量技术,及其管内流动及换热特性。
Slush is a mixture of liquid and solid in which fine solid particles are dispersed in the I/clmd phase. Because of the characteristics such as high density and cryogenic heat capacity, slush hydrogen is being considered as a spacecraft fuel, and slush nitrogen is expected to be an excellent coolant for high temperature superconducting devices. This paper introduces production methods of slush hydrogen and slush nitrogen, density and mass flow rate measurement, pipe flow and heat transfer characteristics.
