对流浆箱内整流元件-湍动发生器进行了基于二相流动的数值模拟。主要是针对阶扩型和渐扩型两种湍动发生器结构形式，通过改变入口流速和湍动发生器结构参数进行了多种情况下的数值模拟计算。探讨了这些因素对湍动发生器的湍动发生性能影响，其结果对湍动发生器的结构优化具有较好的指导意义。

Based on the principle of turbulence generation, the turbulent characteristic and parameters of the paper pulp flow inside turbulence generators were investigated. Considering the turbulence intensity and scale as parameters of the cost function, the computer fluid dynamics-based optimal method for the structure design of turbulence generators was proposed and applied in the design of two classical structure types. The numerical method and the conclusion are applic...
