Hydrodynamic Aspects of Energy Conservation in Commercial Ship Design

摘要

With an ultimate objective of fostering more efficient use of energy in future U.S. Flag merchant ships, pertinent data on novel stern shapes, appendages, and propulsors were analyzed to determine possible degree of improvement, extent of applicability, and needed development relative to improving the speed/power performance of commercial ships. Additionally low block coefficient hull form design state-of-the-art was reviewed to determine adequacy of existing guidance. Concurrently an experimental evaluation of the propulsive effectiveness of a tandem propeller on a high powered containership model was made with promising results.
