NSF-CGP Science Fellowship Program: Adoption of Tokyo University Modified Marker and Cell Program (Tummac) for Invetigation of Free Surface Flow Around Work Boat Hulls

该奖项为新奥尔良大学海军建筑和海洋工程系教授兼主任Robert Latorre教授长期访问日本提供支持，他将于1993年1月至6月与东京大学海军建筑和海洋工程系Hideaki Miyata教授合作。该项目涉及对墨西哥湾使用的驳船、拖船和工作船典型的平坦或钝化船头周围的自由表面流动进行计算机模拟。数值计算将使用东京大学修正的Marker and Cell程序TUMMAC进行。该程序已被用于研究由细长和中等饱满的船体形状以及破浪引起的一些自由表面流动。该研究项目将促进船舶设计和海洋工程领域的技术进步。唯一的问题是将自由面包含在流体动力学方程中。尽管造船活动可能需要一段时间才能恢复到以前的水平，但使用计算机辅助虚拟模拟的船舶设计可能很快就会在国际上以美国为中心。将TUMMAC等代码集成到设计程序中在这一开发过程中非常重要。该项目还将通过计算机和视频教材加强工程学教育。

This award provides support for a long-term visit to Japan for Professor Robert Latorre, Professor and Chairman, Department of Naval Architecture and Marine Engineering, University of New Orleans, who will work with Professor Hideaki Miyata, Department of Naval Architecture and Ocean Engineering, University of Tokyo, from January to June 1993. The project involves computer modeling of the free surface flow around a flat or blunt bow typical of barges, towboats, and workboats used in the Gulf of Mexico. The numerical calculations will be made by using the Tokyo University Modified Marker and Cell program, TUMMAC. This program has been used to study a number of free surface flows caused by slender and moderately full hull forms, as well as breaking waves. The research project will contribute to the advancement of technology in the area of ship design and ocean engineering. The unique problem is the inclusion of the free-surface in the fluid dynamics equations. Although it may be awhile before shipbuilding is restored to its previous level of activity, it may not be so long before ship design using computer aided virtual simulations is internationally centered in the United States. The integration of codes such as TUMMAC into the design procedure is important in this development. The project will also result in enhanced engineering education through computer and video instructional materials.
