The steps toward the fabrication of directly extruded microstructured fiber preforms made of
a bioresorbable phosphate glass are herein presented, analyzing the features of the …

We consider the role of heating and cooling in the steady drawing of a long and thin viscous
thread with an arbitrary number of internal holes of arbitrary shape. The internal holes and …

A series of six experiments drawing tubular fibres are compared to some recent
mathematical modelling of this fabrication process. The importance of fibre tension in …

We consider the flow of a thermoviscous fluid within a vertical tube which is heated from
below, modelling a scenario where a fluid melts, flows and eventually drips due to a …

In the fabrication of optical fibers, the viscosity of the glass varies dramatically with
temperature so that heat transfer plays an important role in the deformation of the fiber …

We consider the stability of the drawing of a long and thin viscous thread with an arbitrary
number of internal holes of arbitrary shape that evolves due to axial drawing, inertia and …

A model is developed for the extrusion in the direction of gravity of a slender fluid cylinder
from a die of arbitrary shape. Both gravity and surface tension act to stretch and deform the …

In the fabrication of optical fibres, the viscosity of the glass varies dramatically with
temperature so that heat transfer plays an important role in the deformation of the fibre …

In a previous study, we compared experiments on drawing of axisymmetric tubular optical
fibres to a mathematical model of this process. The model and experiments generally …

Mathematical modeling is used to examine the unsteady problem of heating and pulling an
axisymmetric cylindrical glass tube with an over-pressure applied within the tube to form …
