MEASUREMENT AND PREDICTION OF THERMOCOUPLE PROBE TEMPERATURES WITHIN GLASS RODS SUBJECTED TO RADIATIVE HEATING
Resumo
Existing data from thermocouple probes inserted into fused
silica glass rods within an optical fiber draw tower furnace
were used for comparisons with modeling predictions.
Radiative transport model through the glass was based on the
zonal method and a four band model with two absorbing and
two non-absorbing bands. The glass rod and thermocouple
probe temperature distributions were computed as a coupled
conduction-radiation problem within the furnace enclosure.
Predicted and measured results were in good agreement in spite to limitations imposed by incomplete knowledge of relevant glass properties and the assumption diffuse glass surfaces.
