Model results for the heating of a fiber-optic cable, to study the heating effect of the PVC tube around which the cable is wrapped to a coil. Input data: - incoming short-wave radiation; - air temperatures (to compute outgoing long-wave radiation and direct heat transfer to the air); - wind speed (to compute heat transport by the hot wire anemometer principle). Output data: - temperatures of the glass fiber inside the cable. Glass fiber temperatures are modeled for a cable that is adhered to a PVC tube and a cable in free air. The differences between both temperatures are compared to actual measurements of the glass fiber temperatures obtained by fiber-optic Distributed Temperature Sensing.
