- 摘要:
- 针对天然气水合物水力提升过程中中继舱部件的沉积安全性问题，为了避免中继舱因沉积过多而导致整个提升系统的瘫痪，利用流场模拟软件CFD，分析了不同结构对中继舱内部流场的影响，对比了正方体、球体和圆柱体3种不同中继舱结构下的颗粒沉积情况、内部流速分布、粗细颗粒以及海水体积分数分布情况，得出圆柱体结构的安全性要优于另外两种结构。研究了圆柱体结构在不同工况下的沉积情况与安全性。结果表明：增加粗颗粒浓度，粗颗粒直径以及粗颗粒的密度都会导致中继舱沉积厚度增加，安全性降低，而增加进口速度则会导致中继舱沉积厚度减小，安全性有所提高。
- Abstract:
- In order to study the deposition safety of relay buffer, which is the most important part in the hydraulic lifting process of natural gas hydrate, so as to avoid the breakdown of the whole lifting system caused by the excessive deposition in relay buffer, the influence of different structures on the internal flow field of relay buffer under the same conditions and volume was studied using the flow field simulation software CFD. The situation of particle deposition, internal flow velocity distribution, particle size and sea water volume fraction distribution of three different structures of relay buffer, including cube, sphere and cylinder, were compared, and it showed that the safety of cylinder structure is better than the other two kinds of structure. The deposition situation and safety of cylinder structure under different conditions were studied with emphasis. The results showed that increasing the coarse particle concentration, coarse particle diameter and coarse particle density will all result in the increase of deposition thickness in relay buffer and the reduction of safety, while increasing the inlet velocity will lead to the decrease of deposition thickness in relay buffer and the improvement of safety.
