Description: | Special report Abstract: Superstructure icing can have debilitating effects on the operation of any ship. When designing ships that will operate in environments where icing may occur, careful consideration must be given to minimizing the accumulation and effect of shipboard icing. Such consideration was given to the Navy DDG-51 class destroyer when new turbine intake louvers were proposed. To ensure that sufficient air would be available to the vessel's gas turbines and ventilation system during an icing event, the U.S. Navy tasked the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) to conduct a series of comparative icing tests between standard intake louvers and a new louver design. Using a test matrix and design parameters supplied by a Navy contractor, CRREL designed a test apparatus and instrumentation suite to carry out the tests. Testing conducted with reconstituted seawater at the CRREL facility demonstrated that, under various icing conditions, the rate of ice accumulation of the two louver designs was very similar. However, the increased number of louver vanes of the proposed design led to more rapid restriction of air accumulation on the vanes. |
