本文的主题是真实船体表面的摩擦阻力，该摩擦阻力是根据应用于实际表面的适当水动力数据确定的。对 40 多种不同粗糙度的数据进行了调查，所有这些都是实际船体表面的复制品或测试模型。通过选择这些表面获得全尺寸平面阻力。讨论了与模型船舶性能预测和维护成本效益分析相关的结果的重要性。本文的核心是对克劳瑟函数的调查，它给出了船体粗糙度在控制阻力时的物理事实。
The subject of this paper is the frictional drag of real hull surfaces determined from the proper hydrodynamic data applied to the actual surfaces in question. A survey of the data is given for more than 40 different roughnesses, all of which are replicas of, or test models of, actual hull surfaces. The full-scale planar drag is obtained for a selection of these surfaces. The significance of the results is discussed in relation to model-ship performance prediction and in connection with cost-benefit analysis of maintenance. The heart of the paper is a survey of Clauser functions, which gives the physical facts of hull roughness as they govern drag.
