| Description | 1. In this project, we have developed a new improved numerical methodology for modelling strongly non-linear wave and breaking wave impact on structures, particularlly looking at the reliability of wave impact pressure prediction and free surface elevations under various breaking wave conditions, including broken wave, aerated, air-pocket and flip-through impact. 2. We have applied both incompressible flow solver and compressible flow solver for predicting breaking wave impact pressure on vertical wall, and conducted detailed comparisons for various wave conditions. The results have shown that though both models have predicted accepted results for impact pressures on the wall, compressible flow solver is able to produce higher peak impact pressure and the pressure oscillation inside the trapped air pocket . 3. Plymouth experiments on breaking waves impact on vertical wall have been reproduced numerically at the University of Bath using the numerical tool, OpenFOAM. Very good agreements have achieved for free surface elevations at a couple of locations in the wave flume, impact pressures and wave force on the wall. This has shown that the numerical tool is capable of modelling breaking wave impact on structures with reasonable accuracy and reliability when proper cell size and time step are used. We have found that flip-through impact causes the largest impact pressure on the wall. 4. Apart from breaking wave impact, solitary wave impact on coastal sea defence was also simulated by the numerical tool and compared with experiments. The results have also achieved very good agreements between the experiments and numerical predictions. 5. Wave impact on FPSO has also been investigated, and compared with the experiments performed in Plymouth wave tank, again good agreement with experimnetal results has achieved. |
| Exploitation Route | 1. Our research outcome have been presented in international conferences, including the 30th IWWWFB Workshop (2015) in Bristol, the 25th ISOPE conference (2015) in Hawaii, the 11th PACOM Conference (2014) in Shanghai, and the 10th UK Young Coastal Scientists and Engineers Conference (2014) in Cardiff. 2. Our research outcome will be published in leading journals. The draft of the journal paper has been circulated to the co-authors in other partner universities. 2. Our research results have been released on our project website. 3. We have organised three project workshops in January 2014 in London, April 2015 in Bath and September 2015 in Oxford for disseminating the research findings to potential end-users (e.g. coastal and marine engineers, the renewable energy industry, the offshore industry, and the research community in the related areas). |
