【摘要】 提出了一种SL型静态混合器的改进结构,对其内部结构加以描述,并对其中两相流的流动场进行分析.考虑实际装置结构内部两相流流动状态下参数之间的相互关系,对其进行理论研究.两相流通过改进的静态混合单元受到撞击、形成分离、绕流以及融合,持续加强混合效果.通过对真实湍流流态所做的解析,可为进一步完善SL型静态混合器的改进结构与参数的选择及优化提供依据.更多还原

【Abstract】 An improved structure of SL type static mixer was presented in this paper.The internal structure was described and two-phase flow field was analyzed.The comprehensive influencing factors were considered during analyzing the relationship of two-phase flowage parameters in practical device,and the theoretical study was carried out.The two-phase flow was impinged,separated,flowed around and merged by the two-phase flow.The mixture effect was strengthened.The analytic calculation was carried out according to the practicable turbulent flow pattern.The results are useful for the structure parameters effectively selection and the characteristic optimization for the improved structure of SL type static mixer.更多还原
