Mathematical Simulation And Physical Model Research On Marine Engineering Wave Propagation And Large Wave Flume Design Verification

As significant parameter in construction of marine engineering, wave condition is the determinant of the project layout design, type and size of anti-wave structures, construction costs and engineering safety, so it is necessary for us to have an in-depth study on wave propagation. Mathematical simulation and physical model test are the most commonly used in the research. However, there are some new-type structures appearing with the large-scale, deeper-water of the marine engineering, the existing physical simulation equipments and experience can not meet the research needs gradually, so the Large Wave Flume will be structured. And the research about the large flume in China is blank, the structural design and function design should be studied. At the same time, it is worth studying that how to use the physical and numerical simulation company to get more accurate results in engineering applications. The details of this paper are as follows:1. Based on thorough study of both domestic and international paper, give a generalization of the offshore mathematical model, especially those including the Boussinesq equation. The paper also analyzes the numerical solution, wave generation, the border condition of a model which is based on advanced Boussinesq equation and higher order Boussinesq equation.2. By participate in "Shandong LNG gas terminal 3D wave model test" research, like model design and production, schemes tests, data collection and analysis are completed. A 2D wave mathematical model of finite difference method with the rectangular nets is setup on the basis of 3D test. On the comparison of the numerical and physical simulation results, analysis in wave incidence condition and porosity are carried out, and some discipline is giving.3. Combine the research topic of "simulation technique of huge wave in Large Wave Flume" research of Large Wave Flume, a 3D simulation flume with scale of 1:10 is established based on the design of the flume. Multi-group trials are carried out in the simulation flume for the verification of large wave flume design.4. A numerical wave model on higher order Boussinesq equation is used to numerical calculation and verification with 3D flume test.
