Abstract: The stretching (or drawing or spinning) of fluid threads has wide-ranging application including in the manufacture of optical fibres and optical fibre preforms, capillary tubes, micro-electrodes, and textile fibres. In recent times, much research has been motivated by microstructured optical fibres (MOFs), having one through to many internal air channels running along the length of the fibre, and which promise a virtually limitless range of fibre designs. Realization of their true potential is, however, hampered by a lack of understanding of the parameters that control the practical achievability of a desired geometrical structure. This mini-symposium is focused on mathematical modelling to yield understanding of the important physics that governs fibre drawing, including initial geometry, draw ratio, temperature, pressurization of any internal air channels, gravity and rotation of the fibre. Mathematical modelling is crucial to solving the practically important inverse problem of determining the initial conditions and draw parameters to achieve a desired geometry for a given application. We will consider recent progress and future requirements.

Forward and inverse modelling to aid fabrication of fibres with complex geometry.
