Solution of Nonlinear Water Wave Problems Using Boundary - Fitted Coordinate Systems,

Abstract

At the David W. Taylor Naval Ship R/D Center the authors have been investigating the application of numerically generated curvilinear coordinate systems to ship wave problems. These are water wave problems with a body present, and this investigation is part of a broader effort over the past few years to develop and test numerical techniques for use in ship performance prediction. Since no one numerical method is best for all problems, and a wide variety of promising methods is available, the work has involved the investigation of the capabilities of various methods. This paper presents an account of their experience in applying numerically-generated coordinate systems to water wave problems and a brief discussion of closely-related efforts underway elsewhere. Application to free-surface potential flow is highlighted since most of our work so far has focused on such inviscid flows. Similar coordinate generation techniques could be used for viscous free-surface problems.
