造纸流程是非常具有挑战性的建模和模拟，如果一个人接受他们的全部复杂性。包括纤维、纤维碎片（细粒）和填料（非有机颗粒）在内的各种颗粒在非稀释悬浮液中以复杂的几何形状和高流速流动并相互作用。不同的模拟方法进行审查，从颗粒级模拟，通过细观尺度模拟的造纸生产线的全流几何形状。它们的应用，造纸和潜在的提供基本的理解，以及直接的过程优化支持进行了讨论。
Papermaking flows are extremely challenging for modelling and simulation, if one accepts their full complexity. A wide range of particles, including fibres, fibre fragments (fines) and fillers (non-organic particles), flow and interact with each other in a non-dilute suspension, a complex geometry and at a high flow rate. Different simulation approaches are reviewed from particle-level simulations, through meso-scale simulations to the full flow geometry of the papermaking line. Their application to papermaking and potential to provide fundamental understanding as well as direct process-optimization support are discussed.
