Modeling the fabrication of hollow fibers: capillary drawing

Abstract

A method for modeling the fabrication of small-scale hollow glass capillaries is developed. The model is based on an asymptotic analysis of the Navier-Stokes equations, which yields a simple closed-form solution for this problem. We demonstrate the validity of this approach using experimental data and use it to make predictions for a range of regimes of interest for the development of microstructured optical fiber technology.
