超音速飛翔体周りの流体解析に対する格子生成法の研究

抄録

In this study, numerical analysis for predicting near-field pressure signatures of supersonic airplane validated to use Automatic Hexahedra Grid Generation Method "HexaGrid" and Fast Unstructured CFD Code "FaSTAR". The model configuration first phase of JAXA's low-sonic-boom concept demonstration project(D-SEND#1) is used in this study. As a result, it was found that high density of grid and shock waves need to be aligned with Cartesian gird in order to accurately grasp near-field pressure signatures of supersonic airplane.
