Numerical Study on Radiative Heat Transfer and Boundary Control of Glass Fibers Cooling Process
Abstract
In this paper we present a set of numerical simulations for the cooling of a cylindrical glass fiber after the splicing process. Due to the glass high melting point, the radiative term must be taken into account. The nonstationary heat transfer equation is solved using code based on the finite element method under different boundary conditions. The effect of the outer temperature field on the temperature gradients inside the fiber (which causes the thermal stress) is analyzed. Based on this type of study, an optimal control of the temperature inside the fiber can be prescribed.
