摘　　要：海洋核能平台2~3年需要拖航至港口进行换料,在其设计的初始阶段对平台拖航阻力的研究至关重要。考虑2种海洋核能平台概念,分析环形月池对平台拖航阻力的影响。采用STAR-CCM+软件对分离式海洋核能平台和一体式海洋核能平台在不同拖航速度时的拖航阻力进行计算。结果表明,随着拖航速度的增大,拖航阻力增加明显;月池的存在使平台周围流场趋于紊乱,导致核能平台拖航阻力增加;对月池增阻机理的分析可为核能平台的设计提供参考。The offshore nuclear power platform needs to be towed to the port for refueling every two to three years,so it is very important to study the towing resistance of the offshore nuclear power platform at the initial stage of its design.Considering two concepts of offshore nuclear power platform,the influence of annular lunar pool on the towing resistance of the platform was studied.The towing resistance of separate offshore nuclear power platform and integrated offshore nuclear power platform at different towing speeds is calculated by using STAR-CCM+sofware.The results show that the towing resistance increases obviously with the increase of towing speed.The presence of lunar pool makes the flow field around the platform tend to be disturbed,which leads to the increase of towing resistance of the nuclear platform.The analysis of the lunar pool drag increase mechanism can provide reference for the design of nuclear power platform.
