Application of the W-transformation to compute the linearised 2-d beach problem potentials

[摘要] The computation of the 2-d beach problem is reconsidered. A method which allows both regular and singular components to be evaluated for arbitrary values of beach slopes through direct application of the W-transformation to a divergent form of the solution integral is established. Previous models were restricted to the very simple beach angles alpha = pi/2k, k epsilon N. Results indicate that the procedure is sufficiently fast that these potentials (so computed) may be used as kernels in future Green function computations. (c) 2006 Elsevier B.V. All rights reserved.
