Combined Diffraction and Reflection by a Vertical Wedge. PCDFRAC User's Manual
Abstract
This report discusses a method for determining the combined diffraction and reflection of monochromatic incident water waves by a vertical wedge of arbitrary wedge angle. The mathematical formulation of the physical problem is briefly presented as well as the analytical solution, although details of the solution are omitted. In addition, the computer program PCDFRAC, which is a PC version of WEDGE, is outlined. The program, which is designed for use with an IBM or IBM-compatible personal computer, calculates the wave height amplification factors necessary for the modification of incident wave heights due to diffraction and reflection. It also calculates the phase of the amplified wave as well as the wave length (based on the Pade approximation of the linear dispersion relation). Program inputs are incident wave period and direction, water depth near the wedge, the internal angle of the wedge (or for wedge angle) , and the locations where amplification factors and phase are required. Keywords: Batch operations; Bessel function; Interactive operation; Personal computers; Semi-infinite breakwater; Vertical wedge; Water wave diffraction; Ocean wave reflection.
