中文摘要
本研究旨在解决目前CFD在飞行器气动设计中的应用问题,如计算结果对物理模型的依赖以及复杂几何形状处理工作量的增加等。考虑到计算机性能的进一步提高,提出了建筑立方体方法,并进行了各种实用算法的研究,其中一项成果是利用K-计算机进行了世界领先的大规模汽车绕流计算。提出的CFD方法可以直接处理极其复杂和不完整的CAD数据用于模拟,这一点具有重要意义。这可能是一项改变飞机和汽车气动设计过程的技术。
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.
