Inviscid numerical simulations of two-dimensional parallel blade-vortex interaction are carried out in the framework of Task one (first year) of the cooperative research activity between JAXA and ONERA on the 'Comparison of CFD (Computational Fluid Dynamics) and BVI (Blade-Vortex Interaction) noise prediction methods for realistic rotors'. The capability of respective JAXA and ONERA Euler methods for an accurate capture of main features of parallel Blade-Vortex Interaction is evaluated. The results from each side are compared quite well to each other and with NASA experiments with the main features well captured. But some discrepancies are found mainly due to different numerical schemes and computation approaches adapted by each organization.
