在造纸过程中，原纸是由低浓度悬浮液开始形成的。根据流程阶段，可以使用不同的模型来更好地理解和执行流程。给出了与造纸过程相关的流体动力学的简短概述，以及包括纤维网络建模和连续机械断裂模拟在内的新方法。所提供的流体动力学结果说明了一些造纸机湿部现象，而固态建模方法可用于从造纸机的干燥部分到多个转换过程。
In papermaking process the base paper is formed by starting from low concentration suspension. Depending on process stage different models can be utilized for better understanding and performance of the process. A short general overview of fluid dynamics related to papermaking process is given as well as new approaches including fiber network modeling and continuum mechanical fracture simulations. The fluid dynamical results presented illustrated some paper machine wet end phenomena while the solid state modeling approaches can be exploited from drying section of a paper machine to the several converting processes.
