Over the past few years we have developed increasingly accurate numerical models of the single phase flow through a papermachine forming fabric. We propose to validate these models by carrying out PIV measurements of the flow through a scale model of a forming fabric. We also plan to expand on these models by including fibre interactions with the forming fabric. Each fibre in the flow will be modeling as a strand of linked spheroids, and the dynamics of the fibres in the forming-fabric flow will be studied. We plan to validate the numerical models by comparison with experimental observations of the interaction of a single fibre with a cylinder surface, which is a simple representation of one filament in a forming fabric. We will study the range of fibre orientations and positions for which a fibre will be hung up on a cylinder.

在过去的几年里，我们开发了越来越精确的单相流通过造纸机成形织物的数值模型。我们建议通过对成型织物的比例尺模型中的流动进行PIV测量来验证这些模型。我们还计划通过包括纤维与成形织物的相互作用来扩展这些模型。流动中的每一根纤维都将被建模为一串相连的球体，并将研究纤维在成形织物流动中的动力学。我们计划通过比较单一纤维与圆柱面相互作用的实验观察来验证数值模型，圆柱面是成形织物中一根细丝的简单表示。我们将研究纤维在圆筒上悬挂的纤维取向和位置的范围。
