Numerical simulation of wire-coating: the influence of temperature
boundary conditions
Polymer Engineering and Science 39 (1999) 2007-2018
Abstract
A finite element program has been used to analyze the wire-coating
process of an MDPE melt. The melt is modelled by a nonisothermal
Carreau model. The emphasis is on predicting an accurate temperature
field. Therefore, it is necessary to include the heat conduction in the
metal parts.
A comparison is made with the results of a simulation that
models the heat conduction in the metal head by means of a Biot boundary
condition. The influence of the wire velocity, inlet temperature and
power-law index will be examined.
