| 1 | Numerical simulation for erosion effects of three-phase flow containing sulfur particles on elbows in high sour gas fields显示文摘Sulfur particles carried by high-speed flow impact pipelines,which may cause equipment malfunctions and even failure.This paper investigates the scouring effect of mist gas containing sulfur particles on elbows in highly sour gas fields.The multiphase-flow hydrodynamic model of the 90elbow was established by using the computational fluid dynamics(CFD)method.The scouring effects of the gasliquid mist fluid with the water-liquid fraction of 20%and particles with the diameter of 0.01 e0.05mm on elbows were explored within the flow velocity range of 0e20 m/s.In addition,the influences of secondary collision,mean curvature radius to diameter(R/D)ratio,inertial force,drag force,and Stokes number on trajectories of sulfur particles were studied.Moreover,the influences of hydrodynamic parameters of multiphase flow on corrosion inhibitor film were analyzed with the wall shear stress as the reference value.Serious erosion mainly occurred in the extrados of elbow as well as the junction between downstream pipeline and the intrados of elbow,the maximum erosion area occurs at 61.9.When the incident position of the particle was far away from the top of the inlet plane,the probability of secondary collision became smaller.Furthermore,the erosion rate decreased with the rise in the R/D radio.The maximum erosion rate of elbow increased with the increase in the Stoke number.The maximum erosion rate reached 0.428 mm/a at 0.05mm particle diameter and 20 m/s fluid velocity.The wall shear stress increased with the increase in fluid velocity and mass flow rate of particle,the fitting function of the wall shear stress curve was the Fourier type.The results indicated that highvelocity particles had a serious erosion effect on elbows and affected the stability of the corrosion inhibitor film.The erosion effect could be retarded by controlling the velocity and diameter of particles.The results provided technical supports for the safe production in highly sour gas fields. | Enbo Zhang Dezhi Zeng Hongjun Zhu Shuanggui Li Dongbo Chen Jie Li Yanyan Ding Gang Tian | 2018 | Petroleum2018，4，2： | 5 |

| 4 | Measurement of Cross Sections for Ba Isotopes显示文摘In the recent decades,great attention has been paid on the heavy ion collisions under intermediate energy^([1~4]).Early studies mainly focused on the nuclear collisions under low and high energy^([5,6]).In low energy nuclear collisions,the behavior of the colliding nuclei is determined by their mean field,while in high energy nuclear collisions it is the collision of individual nucleons in the nuclei that determines the outcome of the reaction. | Xu Yanbing, Yuan Shuanggui, Yang Weifan, Xiao Yonghou, Pan Qiangyan and Li Yingjun | 2001 | IMP & HIRFL Annual Report2001，，1： | 1 |

| 14 | New heavy neutron-rich isotope ^(238)Th显示文摘A new nuclide (238)Th has been produced via multinucleon transferreaction by 60 MeV/u 18O ion irradiation of the natural uranium. The thorium wasradiochemically separated from the fixture of uranium and reaction products. Theactivity of thorium was measured by using an HPGe detector and a planar HPGedetector. The 238Th has been identified for the first time by measuring the growthand decay of the 7-rays from its daughter 238Pa. The half-life of 238Th was determinedto be 9.4f2.0 min. In addition, a new 7-ray of 89.010.3 keV with TI/2=8.911.5minwas found in the 7 spectrum gated with X-rays of Pa and assigned to 238Th P-- decaybased on measurements of transition energy and half life. | XU Yanbing YUAN Shuanggui YANG Weifan LI Zongwei MA Taotao XIONG Bing HE Jianjun(Institute of Modern Physics, the Chinese Academy of Sciences, Lanzhou 730000) | 1999 | Nuclear Science and Techniques1999，10，2： | 0 |
