| Research Abstract |
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.
