| Résumé | The Science Engineering and Associates (SEA) Ice Crystal Detector (ICD) is an aircraft mounted hot-wire probe used to measure the bulk water content of clouds. The probe uses two wires, in concave and convex elements, which are heated to a constant temperature and evaporate cloud hydrometeors on contact. Generally, these wires are heated to 140◦C and the impact of other temperature settings has not previously been investigated. This work reports on tests performed at the National Research Council’s Altitude Icing Wind Tunnel in order to investigate how the probe measurements differ when the wire set temperature is varied from 20◦C to 160◦C, depending on the ambient conditions. It was found that the probe is able to operate with wire temperatures ranging from 80◦C to 160◦C. However, the calculated power loss due to convection must be modified in order to account for the temperature of the deicing heater on the probe. Since the deicing element is larger than the hot-wires, it requires more time to heat up to its set temperature of 50◦C, which was not considered in this study. It is recommended that measurements with the ICD include a plan to mitigate the impact of the deicing element. |
