Description

Special Report
Abstract: To gather empirical data on ship superstructure icing upon which to base and verify a computer model that can be used to predict icing events, the U.S.Army Cold Regions Research and Engineering Laboratory was asked by the U.S. Navy David Taylor Ship Research and Development Center to create a prototype system capable of collecting relevant spray and icing data on ship decks during cold-weather cruises. The resulting ship icing instrumentation can be divided into two parts: a video system to obtain a visual record of spray and icing and several stand-alone instrumented units to obtain quantitative data. The units are capable of measuring liquid water content of spray fluxes in either the horizontal or vertical directions, measuring ice accretion in either direction, and monitoring several other parameters such as temperature and power level. Problems associated with salt water rendered most of the spray data collected during a cruise aboard the USCGC Midgett unusable. Some problems with surface roughness may have degraded the ice thickness data. Otherwise, the equipment worked quite well. Furtherwork on using a capacitance gauge to measure salt water levels needs to be conducted before the equipment is redeployed at sea. NOTE: This is large.
