Analysis of Wave/Object Interaction Using Distributed Source Elements of Linearly Varying Strengths.

Abstract

Various computer-oriented numerical schemes are available to evaluate the velocity potentials for inviscid fluid flow past submerged objects. The use of a surface distribution of sources of uniform strength over panels representing the object's surface requires a relatively fine grid to obtain accurate results. A new variation of this scheme using distributed sources of linearly varying strengths over triangular panels appears to reduce the number of panels needed for good results, thereby reducing computer time and storage requirements. In the present study, this technique is applied to the problem of determining fluid forces and dynamic response from interaction between an arbitrarily shaped object and surface waves. (Author)
