In the present study, the flow of a fibre suspension in a channel containing a cylinder was numerically studied for a very low Reynolds number. Further, the model was validated against previous studies by observing the flexible fibres in the shear flow. The model was employed to simulate the rigid, semi-flexible, and fully flexible fibre particle in the flow past a single cylinder. Two different fibre lengths with various flexibilities were applied in the simulations, while the initial orientation angle to the flow direction was changed between 45° ≤ θ ≤ 75°. It was shown that the influence of the fibre orientation was more significant for the larger orientation angle. The results highlighted the influence of several factors affecting the fibre particle in the flow past the cylinder.

单缸柔性纤维颗粒相互作用的模拟
在本研究中,对非常低的雷诺数进行了数值研究,研究了纤维悬浮液在包含圆柱体的通道中的流动。此外,通过观察剪切流中的柔性纤维,对模型进行了先前的研究验证。该模型用于模拟流过单个圆柱体的刚性,半柔性和全柔性纤维颗粒。在仿真中应用了两种具有不同柔韧性的不同纤维长度,而相对于流动方向的初始定向角在45°≤θ≤75°之间变化。结果表明,较大的取向角对纤维取向的影响更大。结果突出显示了影响流经圆柱体的气流中纤维颗粒的几个因素的影响。
