| 摘 要： | 建立了自发凝结和异质凝结流动统一的数值模型,研究了存在外界凝结核心时天然气中己烷蒸气的节流凝结性质,并对初始颗粒半径、初始颗粒浓度、背压比和总温等因素对己烷凝结性质的影响进行了分析.计算结果表明,己烷在节流后很短距离内凝结,凝结时间很短；己烷自发凝结的极限过饱和度很高；外界核心引起的异质凝结比较显著时会抑制自发凝结,使...

| Abstract: | If there are foreign nuclei(solid particles or liquid droplets etc.)existing in natural gas flow,condensation of hexane would take place on the foreign nuclei,and thus both homogeneous and heterogeneous condensation would occur in the throttling process.A uniform mathematical model for homogeneous and heterogeneous condensing flow was built to study flow field characteristics and condensation properties of hexane in the throttle valve.The effects of initial particles radius,concentration of the nuclei,back ... |
