摘要/Abstract

摘要： 通过自制热电偶、自制双平行电导探针、Labview编程系统和IMP温度采集系统等测量手段获取油水两相流内部的相分布特征，分析流型种类和流动参数与换热系数的相互影响。结果表明，管外冷却换热会影响流型分布，管外冷却换热过程中水包油、混合界面分层流以及油包水这三种流型所占的范围变小，但分层流、油包水&水包油以及水包油&水流型在流型图上所占范围变大，相邻流型之间的转化分界线偏上，向更大油速和水速趋势发展，并且换热系数与流型和流速密切相关，低流速下主要受流速的影响，而高流速下主要受流型的影响。

Abstract: The self⁃made thermocouple, self⁃made double parallel conductivity probe, Labview programming system and IMP temperature programming system were used to obtain the phase distribution characteristics of oil⁃water two⁃phase flow, and the interaction between flow pattern and flow parameters and heat transfer coefficient was analyzed. The results show that the cooling flow process affects the flow pattern distribution, which means the range of oil⁃in⁃water and mixed interface layered flow and water⁃in⁃oil flows with cooling convection heat is smaller, but the stratified flow, water⁃in⁃oil & oil⁃in⁃water and oil⁃in⁃water & water flow types have a larger range on the flow chart, and flow pattern transition boundary between the two is higher, and the trend of higher oil velocity and water velocity is developed. The heat transfer coefficient is closely related to the flow pattern and flow velocity. The low flow velocity is mainly affected by the flow velocity, while the high flow velocity is mainly affected by the flow pattern.
