这项工作的目的是表征面团在揉捏过程中受到的各种变形，并调查混合机的配置和操作条件的影响。几个捏合机的几何形状被建模为在各种混合器中发生的混合机制的代表。基于获得的随时间变化的速度场，在混合器中发生的变形的类型的特征在于使用相关的运动流分类参数。然后这些参数与捏合机的机械作用相关。揉面机的实际设计的结果可以应用，和一个互补的实验程序应适合在设计周期内。
The objective of this work is to characterize the various deformations to which dough is subjected during kneading, and to investigate the influence of mixer configurations and operating conditions. Several kneader geometries are modeled as representative of the mixing mechanisms taking place in various mixers. Based on the time-dependent velocity fields obtained, the type of deformation taking place in the mixers is characterized using relevant kinematic flow classification parameters. These parameters are then related to the mechanical action of the kneader. The results for the practical design of dough kneaders can be applied, and a complementary experimental program should fit within the design cycle.
