Abstract


Complex terrain conditions , moisture gathering and transportation pipeline effusion regular research, engineering design and operation and management of the natural gas pipeline has a very important significance . In this paper, the experimental operation of the ups and downs of piping, low liquid holdup conditions as the basis , to explore the formation mechanism of the gas-liquid two - phase flow fluid , influencing factors and distribution law . Effusion factors affecting the formation can be divided into three categories: the composition and physical properties of the fluid medium , the geometry of the pipe conditions and experimental operating conditions . First , from the angle of the influencing factors and force to analyze the causes of the effusion , and because of the flow patterns within the piping tube gas, liquid distribution and changes in the most intuitive performance , so the various factors on the flow tube change and held regular liquid distribution . Established on the basis of the two-fluid model of gas-liquid two-phase flow transient multiphase model , namely the establishment of a gas and liquid phase continuity equation and energy equation , taking into account the role of the gas and liquid phases . Calculation of fluid properties , the BWRS equation . Model to solve a fourth-order Runge - Kutta method . The experimental part of the gas-liquid two-phase flow simulation laboratory in China University of Petroleum (East China) Pipeline and Civil Engineering , The experiment operating conditions and low liquid holdup conditions in the undulating line . Experimental data processing using the mathematical model and OLGA simulation software built to solve computing , and experimental measured data were compared to verify the feasibility of the model .
