中文摘要
本研究旨在解决当前CFD在飞机气动设计应用中存在的计算结果对物理模型的依赖以及处理复杂几何形状时工作量增加等问题。考虑到计算机性能的进一步提高,提出了Building-Cube方法,并进行了实际应用的各种算法研究。其中一项成果是利用K-computer围绕一辆汽车进行的世界领先的大规模流动计算。所提出的CFD方法可以直接处理极其复杂和不完整的CAD数据进行仿真,具有重要的意义。这可能是飞机和汽车气动设计过程中的一项颠覆性技术。
英文摘要
This study was conducted aimed at solving the problems of the current CFD in the use of the aerodynamic designs of aircrafts, such as the physical model dependence of the computational results and the increase of the work load for treating complex geometries. The Building-Cube Method was proposed bearing the further performance improvement of computers in mind, and the various algorithm studies for practical use were conducted.One of the achievements was demonstrated by the world-leading large scale flow computation around a car using the K-computer. It is significant that the proposed CFD approach can treat extremely complicated and incomplete CAD data directly for the simulation. This can be a game-changing technology for aerodynamic design process of aircrafts and automobiles.
