| Abstract | Computational aerodynamic studies were conducted to investigate the centerbody effects on the aerodynamic characteristics of delta wings with sharp leading edges. Vortical flows around IAR 65° delta and 55° diamond wings were simulated using Computational Fluid Dynamics (CFD). Two flow solvers were employed to compute steady inviscid flows over with and without centerbody configurations of the two wings. These two solvers are an IAR in-house code, FJ3SOLV, and the CFD-FASTRAN commercial software. The computed flow solutions of the two solvers have been compared and correlated against the IAR Pressure Sensitive Paint (PSP) measurements. The major features of the primary vortex were well captured and overall reasonable accuracy was obtained. In accordance with the experimental observations for the flow conditions considered, the CFD computations revealed no major global effects of the centerbody on the surface pressure distributions of the wings. However, CFD-FASTRAN seems to predict a vortex breakdown, which is neither predicted by FJ3SOLV nor observed in the wind tunnel for the simulated flow conditions. |
