摘要
围绕船舶的能效设计指数(EEDI)和能效运营指数(EEOI)标准的制定和实施,如何降低航行船舶的能耗和废气排放一直是人们关注的热点。基于SHIPFLOW软件模拟船后不同布局的预旋三角导管对阻力、自航因子和各效率的影响,优选出性能较好的布局,并通过水池试验验证。为船舶节能装置的设计和应用提供数值参考。
Around the formulation and implementation of EEDI（energy efficiency design index） and EEOI（efficiency of operation index） standards of ships, how to reduce energy consumption and emissions during ship＇s navigation has been the focus of attention of the people. The influence on the resistance, propulsive factors and efficiencies through different after-ship Pre-Swirl Delta duct arrangements are simulated using SHIPFLOW software, and validated through tank experiments. This study can provide some numerical reference for the design and application of ship energy saving devices.
