During the drawing of optical fibers in an enclosed furnace the heat transfer to the fiber is due to both radiation from the furnace walls and free convection from the ambient gas. The stability of the free convection is a function of the furnace wall temperature distribution and of the iris temperatures. Experimental results are presented that show how the iris temperature affects the frequency of the convective flow oscillation in a simplified annular geometry. The flow possesses hysteresis in that as the iris temperature is increased and then decreased, the oscillatory flow does not return to its initial condition. All of the flow behavior studied in the annular geometry was three-dimensional.
