节能阻流板诱导升力函数化研究

节能减阻是近年来国际上关注的热点，船舶行业作为能耗和排放重点行业，面临着巨大的压力和挑战。目前可能采用的节能减阻方法在节能效果、成熟程度和实施手段方面均存在一定的不足，阻流板能够较好的解决以上问题，对绿色船舶的发展，新船型的开发和旧船型的改良有积极的意义。本项目拟基于粘性流体力学理论，采用数值模拟预报规律、模型试验验证和修正相结合的方法，对阻流板诱导升力进行研究。建立用于捕捉大、小尺度物体间水动力干扰的系统的数值模拟方案，研究阻流板诱导升力和各独立影响因素之间的关系，探讨多因素耦合作用下升力的变化规律，并通过试验对计算方案和单、多因素作用下升力变化规律进行验证和修正，对阻流板绕流场进行观测和分析。通过本项目的开展，可望在理论上揭示阻流板诱导升力的函数表达式和阻流板的水动力机理，并验证函数关系的可靠性和实用性，为低成本解决船舶节能减阻、降低排放量和提高旧船型水动力性能奠定理论和技术基础。

In recent years, one of the hotspots is to reduce resistance and save energy, and the shipping project is faced with enormous pressure because of energy consumption. The traditional methods used for energy-saving all have shortages, but interceptor is a power tool to solve the problem compared with them. It is significant in the development of the green ships, design of the new ships and improvement of the old vessels. This research is carried out on basis of the theory of viscous fluids, and the methods of numerical simulation and model test are both used to investigate the lift force induced by interceptor. An alternative set of computation parameters are suggested for the calculation of the hydrodynamic interaction, the relationship between the lift force and each factor/factors influencing the force are investigated, and the model test is carried out on the purpose of verification and modification. The flow field is also observed and analysed by the test. The function of the induced lift force will be obtained and checked by this research, the hydrodynamic mechanism of interceptor is presented, and the low-cost method offers a possibility for energy-saving and improvement of the hydrodynamic performance of the old ships.
