This book was released on 2020-12-29 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine propulsors are key components of the many thousands of ships and boats operating in oceans, lakes, and rivers around the world. The performance of propulsors are important for the environmental impact of ships, underwater noise impact on aquatic fauna, and crew and passenger comfort and safety. This book presents nineteen papers devoted to the hydrodynamics of different types of marine propulsors (conventional propellers, thrusters, and novel solutions). Most of the papers are extended papers from the sixth International Symposium on Marine Propulsors (SMP 2019). Several of the papers deal with cavitation, vortices, and energy saving devices. The papers present high-quality research performed using Computational Fluid Dynamics (CFD) and Experimental Fluid Dynamics (EFD) as well Artificial Intelligence (AI).

This book was released on 2021 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, a systematic procedure of analyzing marine propeller performance and its underwater acoustics is delineated. The main focus is laid on the numerical prediction of hull pressure fluctuations and far-field acoustics induced by marine propellers via frequency- or time-domain approaches. As the first step, a hydrodynamic boundary element method (BEM) is implemented to analyze the comprehensive marine propeller performance in open water and ship-behind conditions. An elaborate numerical scheme modeling developed tip vortex cavitation is proposed for cavitating propellers. In the frequency domain approach, a potential-based panel method (or pressure-BEM) solving for the diffraction potential on the ship hull is coupled with the hydrodynamic BEM to predict the propeller-induced hull pressure fluctuations. Infinite speed of sound is assumed in the near-field, neglecting the time travel of acoustic waves to reduce the Helmholtz equation to the Laplace equation, which can be solved by a standard BEM solver. Far-field underwater noise is investigated in the time domain using the Ffowcs Williams-Hawkings (FW-H) formulation. The model propeller is mounted on the ship with an infinite plane assumed at the design draft to consider the pressure release or solid wall boundary conditions. Time-dependent surface quantities from the hydrodynamic analysis are taken as the known noise sources to the FW-H equation given in the form proposed by Farassat. The complex hull geometry and its disturbance to the medium are considered by solving the boundary integral equations. A half-space domain is modeled by modifying standard full-space Green's function to consider the image model beyond the infinite plane. The propeller-induced noise, its reflections from the hull, and their sums as the total noise will be investigated in full-space or half-space domains. Numerical predictions, including the time history of acoustic pressures and noise spectra, under various operating conditions are compared with experimental measurements, observations, and results from finite volume methods to validate the feasibility and accuracy of the present method
