漂移流模型分析两相自然循环系统静态漂移特性的探讨
Investigation on the Static Flow Excursion in Two-phase Natural Circulation System Using the Drift-flux Model
【摘要】 基于分岔理论及其DERPAR数值方法,运用漂移流模型分析典型两相自然循环系统的静态分岔解图,并与均相流模型的结果进行了比较。结果表明:与用均相流模型得到的解图相比,用漂移流模型得到的静态分岔解图的不稳定运行区域和输热能力限相对较小。
【Abstract】 Based on the theory of bifurcation and its DERPAR algorithm, the static bifurcation solution diagram of a typical twophase natural circulation system is analyzed using drift flux model, and compared with the results of homogenous model. The results show that the unsteady area and heat transport ability of the diagram based on drift flux model are smaller than that of the diagram based on homogenous model.
