| Abstract | This laboratory technical report presents the results of bulk cloud water content measurements taken with the Ice Crystal Detector and Nevzorov probes at the Altitude Icing Wind Tunnel of NRC. The Nevzorov and Ice Crystal Detector are aircraft-mounted hot-wire probes designed to find the bulk water content of clouds and are being used as the NRC Convair 580 aircraft core sensors. These two probes were tested in the NRC Altitude Icing Wind Tunnel facility in late 2020 and early 2021 in order to characterize their responsiveness to liquid water in a controlled environment. The probes were tested at a variety of liquid water content set points, particle median volume diameter, true air speed, pressure, and temperature. Measurements of the liquid water content and total water content were made in a setting of pure liquid conditions, and the probes measurements were compared to wind tunnel nominal values. The calculation of dry power loss for the Ice Crystal Detector was improved using a modified fit in the clear air. Icing was observed on both Nevzorov reference wires, creating a false signal and unreliable data, leading to the conclusion that the dry power loss should be calculated using the ambient parameters similar to how it is done for the Ice Crystal Detector. |
