ABSTRACT This proposal deals with manufacturing of coated optical fibers at high draw speed (e.g. 20 m/s). The quality of the fiber depends on the diameter and concentricity of the coating, coat layer continuity, smoothness, bubble inclusion, and uniformity. These characteristics are in turn affected by heat transfer and fluid flow that occur during the coating process. The Principal Investigators (PIs) propose a theoretical and experimental program to study the transport processes and determine the effects various operating parameters have on the aforementioned characteristics. Numerical simulations that take into account non-Newtonian effects and variable properties will be carried out. Experiments will be conducted using different coating applicator geometries, coating materials, draw speeds, and fiber materials. The experimental results will be used in conjunction with the simulation results to establish the linkage between the operating parameters and the quality of the fiber. Validation of the numerical model will also be performed. The results from this study will be useful for the design and optimization of coating dies and applications under different conditions.

本方案涉及高拉速(如20m/S)镀膜光纤的制造。纤维的质量取决于涂层的直径和同心度、涂层的连续性、平整度、气泡夹杂物和均匀性。这些特性反过来又受到涂层过程中发生的热传递和流体流动的影响。首席调查员(PI)提出了一个理论和实验方案来研究输运过程，并确定各种操作参数对上述特性的影响。将进行考虑非牛顿效应和可变性质的数值模拟。实验将使用不同的涂布器几何形状、涂布材料、拉伸速度和纤维材料进行。实验结果将与模拟结果相结合，以建立操作参数和光纤质量之间的联系。还将对数值模型进行验证。研究结果对不同条件下涂层模具的设计、优化及应用具有一定的参考价值。
