Energy saving by using asymmetric aftbodies for merchant ships-design methodology, numerical simulation and validation

摘要：

　　The methodology and procedures are discussed on designing merchant ships to achieve fully-integrated and optimized hull-propulsion systems by using asymmetric aftbodies.Computational Fluid Dynamics (CFD) has been used to evaluate the powering performance through massive calculations with automatic deformation algorisms for the hull forms and the propeller blades.Comparative model tests of the designs to the optimized symmetric hull forms have been carried out to verify the efficiency gain.More than 6% improvement on the propulsive efficiency of an oil tanker has been measured during the model tests.Dedicated seatrials show good agreement with the predicted performance from the test results.
