船舶流体力学中若干逆问题的研究

在船舶流体力学中，给定物体（船、桨、附体或其组合体），要求确定其在不同的运行状态和环境条件下的某种性能（如阻力、运动等等）或周围的流场，这种问题称为正问题．与此相反，若给定物体的性能要求或场的信息，寻求满足要求的物体，就是逆问题．本文通过船舶流体力学中若干逆问题（如给定表面速度分布时螺旋桨桨叶剖面设计、轴对称物体设计等等）的介绍和讨论，对逆问题研究的特殊性、实用性及可能的发展方向作简要的评述．

SOME INVERSE PROBLEMS IN SHIP HYDRODYNAMICS

in ship hydrodynamics, the determination of performances (such asresistance, motion characteristics etc.) of a given ohject or the flow field around the object under various running conditions and environmental conditions is known as the direct problem. On the contrary, in some case, we will have to find a suitable object having given performances or given flow field characteristics, which is the so called the inverse problem.The aim of the present paper is to make some comments on the special features and the practical use of the inverse problems as well as the possible development through the discussion on some typical,inverse problem in ship hydrodynamics, such as the design of 2-D wing sections and axisymmetrical bodies under the given surface velocity or pressure distribution etc.
