Verification of Numerical Wave Tank Predictions for Multi-Directional Seas

9720427 Roesset该奖项为德克萨斯农工大学/得克萨斯大学奥斯汀分校的工程研究中心提供资金，题为“离岸技术研究中心”(OTRC)，与麻省理工学院(MIT)、挪威科技大学(NTNU)和MARINTEK(挪威科技大学的商业/研究波盆运营)的研究人员合作，对这些机构的数值波盆模拟器和波盆实验的分析结果进行基准测试。将对OTRC、MIT和NTNU开发的数值波浪水槽和算法的结果与OTRC和MARINTEK使用挪威石油公司挪威国家石油公司提供的圆柱体和微型张力腿平台进行的物理波盆测试的实验数据进行比较。这一基准将导致改进的数值波浪水槽模型和改进的物理波盆中的波浪运动学，用于再现多方向的海况以及在侧面反射的条件和影响下作用于建筑物的力。最终，发展良好的数值波浪水箱将能够补充或取代一些非常昂贵的物理模型试验。

9720427 Roesset This award provides funding for the Engineering Research Center at Texas A&M University/University of Texas at Austin entitled "Offshore Technology Research Center" (OTRC) to work with researchers from the Massachusetts Institute of Technology (MIT), the Norwegian University of Science and Technology (NTNU) and MARINTEK (NTNU's commercial/research wave basin operation) to benchmark analytical results from numerical wave basin simulators and wave basin experiments at these institutions. Benchmarking will be done comparing the results of the numerical wave tanks and algorithms developed at OTRC, MIT, and NTNU with experimental data from physical wave basin tests at OTRC and MARINTEK using a cylinder and a mini tension leg platform provided by the Norwegian oil company STATOIL. This benchmarking will lead to improved numerical wave tank modeling and improved wave kinematics in a physical wave basin used to reproduce multidirectional sea states and the forces acting on structures under the conditions and effects of side reflections. Eventually, well-developed numerical wave tanks will be able to complement or replace a number of very expensive physical model tests.
