摘要Kirti N.辛辛那提Ghia大学提案编号CTS-9512450 辛辛那提大学的航空航天工程和工程力学系以及机械、工业和核工程系将购买Silicon Graphics公司的高性能图形计算机系统，专门用于支持计算流体动力学和热科学系的研究活动以及研究生的学术追求。 拟议的仪器将用于研究高雷诺数流动现象的基本流动物理学的项目，即一般不稳定性，过渡，湍流和混沌，使用大涡和直接数值模拟，以及应用工程问题，如压力畸变的发动机风扇平面上的亚音速进气道在侧风的存在。 它还将用于涉及流体动力学、飞行力学和结构力学领域问题的跨学科研究，如机动体和气动弹性问题。

ABSTRACT Kirti N. Ghia Univ. of Cincinnati Proposal No. CTS-9512450 The Department of Aerospace Engineering and Engineering Mechanics and the Department of Mechanical, Industrial and Nuclear Engineering at the University of Cincinnati will purchase Silicon Graphics high-performance graphics computer systems, which will be dedicated to support research activities of faculty in computational fluid dynamics and thermal sciences and the scholarly pursuits of graduate students. The proposed instrumentation will be used in projects for studying fundamental flow physics of high-Reynolds number flow phenomena, namely general instabilities, transition, turbulence and chaos, using large-eddy and direct numerical simulations, as well as applied engineering problems such as pressure distortions on an engine fan plane on a subsonic inlet in presence of cross-wind. It will also be used for interdisciplinary research involving problems in areas of fluid dynamics, flight mechanics and structural mechanics, such as maneuvering body and aeroelasticity problems.
