Air flow induced by the motion of the glass and by natural convection affects the heating and cooling of the material during the optical fiber drawing process. This flow is also responsible for impurity transfer on the surface of the fiber during processing. This paper presents results of a numerical simulation of the convective air currents in both the heating region (furnace) and the cooling region of the drawing process. For the heating region the case of an empty furnace, a furnace with a stationary glass preform and a furnace with a moving preform were examined. For the cooling region studies were performed for the case of pure forced, pure natural and mixed convection. Air velocity profiles are presented in graphical form.
