Description:This classic textbook fills the need for a single volume on the applications of hydrodynamics to marine problems. The book is solidly based on fundamentals, but it also guides the student to an understanding of engineering applications through its consideration of realistic configurations. The book takes a balanced approach between theory and empirics, providing the necessary theoretical background for an intelligent evaluation and application of empirical procedures.
The applications of hydrodynamics to naval architecture and marine engineering expanded dramatically in the 1960s and 1970s. This classic textbook, originally published in 1977, filled the need for a single volume on the applications of hydrodynamics to marine problems. The book is solidly based on fundamentals, but it also guides the student to an understanding of engineering applications through its consideration of realistic configurations. The book takes a balanced approach between theory and empirics, providing the necessary theoretical background for an intelligent evaluation and application of empirical procedures. It also serves as an introduction to more specialized research methods. It unifies the seemingly diverse problems of marine hydrodynamics by examining them not as separate problems but as related applications of the general field of hydrodynamics.
A Computational Fluid Dynamics (CFD) model to simulate the water and air flow around competition kayak hulls was developed, with the principal aim of allowing accurate drag force predictions. These model used the Volume of Fluid (VoF) method to determine the location of the free surface, and the k-ω Shear-Stress Transport (SST) to account for turbulent effects. The open-source CFD software package OpenFOAM was used for this purpose, namely its solver application interFoam. The model was first tested on the Wigley hull, a typical validation case for models of flow around marine vessels. Effects of mesh refinement and alteration were studied, and the results for total drag force and hull wave profiles were obtained from the model for several different Froude numbers. Drag force was calculated for a wide range of velocities and compared to experimental data and to other numerical results. The drag forces obtained for the kayak models was generally close to experimental results up to velocities around 3.69 m/s, after which the numerical model underestimated the value of the total drag. 153554b96e
