端面造型载体催化器结构优化设计

Structure optimum design of end sculpt catalyst converts

采用ANSYS-CFD软件,对具有良好流动特性的端面造型载体催化器进行了二维稳态流动数值模拟,分析了载体端面型式、位置、匹配关系等对流动特性的影响。研究表明:锥形端面载体的锥角为90°时可使催化器获得较均匀的流速径向分布和较小的压力损失。从均匀性与结构紧凑性方面考虑,载体应位于扩张段的起始位置。

It adopts ANSYS-CFD software,steady flows numerical simulates end sculpt substrates that have well flow speciality,and analyses the influence of the end type of the substrate ,location,matching connection to flow speciality. The studies indicate that cone-shaped end substrate when the cone is 90° can obtain well-proportioned velocity distributing and lesser pressure lose. Subtract ought to locate initiative institute of diffusion from the advisement of the uniformity and structure compaction.
