摘要/Abstract

摘要：

浆氢是固氢和液氢的混合物，相比于液氢由于浆氢具有更高的密度和热容，更适合用于火箭和航天推进器的推进剂。基于欧拉-欧拉两相流模型，在考虑颗粒动力学的基础上对浆氢在水平圆管中的流动与传热特性进行了数值模拟研究。通过对浆氢在不同热通量、流速和颗粒直径等情况下的研究发现，浆氢相比于液氢可以有效减少液氢气化。流速的提升能够有效提高固相颗粒分布的均匀性，且使得浆氢沿程平均传热系数增大。小直径的固相颗粒相比于大直径颗粒能够增强固液两相间的换热，加快浆氢的融化。

Abstract:

Slush hydrogen is a mixture of solid hydrogen and liquid hydrogen.It can be used as the fuel of rocket and space booster compared with the liquid hydrogen due to the higher density and heat capacity.In the present study, a numerical model was built based on the Eulerian-Eulerian model and kinetic theory of granular flow to investigate the flow and heat transfer characteristics of slush hydrogen in a horizontal pipe.For different heat fluxes, flow velocities and particle diameters of the slush hydrogen, it was found that the temperature of fluid can be decreased while using slush hydrogen instead of liquid hydrogen so that the vaporization of liquid hydrogen can be suppressed.The increase of flow velocity can make the distribution of particle more uniform and enhance the average heat transfer coefficient of slush hydrogen along the tube.Small diameter particle can improve the heat transfer between the solid phase and liquid phase and the melting of slush hydrogen can be accelerated.

Key words: slush hydrogen, flow and heat transfer, volume fraction distribution, Eulerian-Eulerian model
