Residual Resistance of Displacement Vessels

Ada Gotman

The hydrodynamics of the residual resistance of ships is formulated for the first time: the residual resistance of vessel displacement is the result of the formation of retaining bow waves, Kelvin wave systems and their interaction—as well as the action of viscosity, which is expressed in the form of a turbulent subsurface boundary layer. Michell’s integral is taken as a basis for calculations of residual resistance. The two corrections take into account the shear layer of wave surface and the shift of the Kelvin bow system by the retaining waves. The correlation of the calculated and experimental curves confirms the validity of the described hydrodynamics of residual resistance. This article is intended for specialists in the field of hydrodynamics of displacement vessels and for designers of the ship hull.

排水管的残余阻力

船舶残余阻力的流体力学是第一次被公式化:船舶位移的残余阻力是滞留弓形波,开尔文波系统及其相互作用以及粘性作用的结果。呈湍流地下边界层的形式。密歇尔积分是计算剩余电阻的基础。两次校正考虑了波浪面的剪切层和保持波对开尔文弓形系统的偏移。计算曲线与实验曲线的相关性证实了所描述的剩余阻力流体动力学的有效性。本文适用于置换船流体动力学领域的专家和船体设计人员。
