碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 96 / The objective of the research is to apply Boussinesq equations to develop a series of numerical calculations to simulate the affaction of wavehight changes that because two dimensional wave passing through cylinders. This article is based on the concept of Nwogu (1993) that expressed by random depth and the fourth-order Adams-Bashforth-Moulton predictor-corrector scheme in coordination with source function and proper damping boundary conditions to increase the stability of calculation and to decrease the required processing time.The results are quite well in comparison with previous research. In the numerical calculation,first in the geography of 5 meters depth ,we think about that wave of the period is 3.5 seconds and 5 seconds pass through the cylinders of the radious is 3 meters and make waveheight changing.The two cases that one is setting two cylinders shows the wavehight that in the front of the cylinder is approximately 1.7 times the H0,and another is setting four cylinders shows the wavehight that in the front of the cylinder is approximately 1.8 times the H0. Additionally, the numerical calculation can to simulate that wave pass through a group of cylinders in different depth making wave transformations. So the numerical calculations apply to simulate wave pass through cylinders making wave transformations in constant depth、varying depth .
