The visualized images of drag production were got from the far-field analysis and they gave good insight of production of drag.

Abstract
Far-field drag analysis was performed on computational fluid dynamics simulation re- sults of the NASA Common Research Model performed in JAXA for the Drag Prediction Workshop 4. Three levels of grid were employed in that simulation and the far-field anal- ysis successfully acquired close values to the converged drag value estimated by near-field analysis of convergence study for all levels of grid. Drag decomposition in far-field analysis also revealed which part of the flow and which component of the drag varies for variation of angle of attack. The visualized images of drag production were got from the far-field analysis and they gave good insight of production of drag.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
