Beskrivning

This book deals with flows over propellers operating behind ships, and the hydrodynamic forces and moments which the propeller generates on the shaft and on the ship hull. The first part of the book is devoted to fundamentals of the flow about hydrofoil sections and wings, propellers in uniform flow and pragmatic design guides for analysis and performance. The second part covers the development of unsteady section and blade forces arising from operation in non-uniform hull wakes. The problem of a non-cavitating, wide-bladed propeller in a wake is treated by a new and completely developed theory. A final chapter discusses the optimisation of efficiency of compound propulsors. The authors have taken great care to clearly describe physical concepts and mathematical steps. An appendix provides a concise introduction to (or reprise of) the mathematical techniques used.
