摘要
浆氢作为低温浆态推进剂具有良好的能量密度和流动特性,被认为是未来火箭的重要燃料和中子源冷却剂,但是浆氢在管道中复杂的固液两相流动机理以及制备技术限制了其应用领域的发展。因此归纳了浆氢研究的发展脉络,综述了浆氢的热物理性质、制备及测量方法、流动传热特性等关键问题,比较了不同制备方法的原理及优劣势,概括了输送中管道压降和传热机理,重点分析浆氢在输送中存在的沉降分层、漏热振荡等应用问题,并探讨了浆氢技术未来的发展趋势,以推动浆氢在航天领域的工程化应用。
Slush hydrogen,characterized by its commendable energy density and superior rheological properties at low temperatures,is considered a pivotal fuel for future rocket propulsion and a coolant in neutron sources.However,the complex mechanisms of solid-liquid two-phase flow and the limitations inherent in current preparation technologies curtail its broader application within the field.This review delineates the development trajectory of slush hydrogen research and sums up pivotal discussions on its thermophysical properties,methodologies for preparation and measurement,alongside flow and heat transfer dynamics.Comparative analyses of various preparation methodologies elucidate their underlying principles,merits,and demerits.Furthermore,the paper encapsulates the challenges of pipeline pressure drops and heat transfer mechanisms during transit,with a concentrated examination of issues such as sedimentation stratification and thermal leakage oscillations encountered in the transportation of slush hydrogen.Finally,prospective trends in slush hydrogen technology are addressed with an aim to augment its integration into aerospace applications.
