| Abstract: | The unsteady transonic flows around a pitching slender delta wing are simulated numerically with solving unsteady compressible Navier-Stokes equations by implicit finite difference TVD scheme. The unsteady flowfield structures, the features of vortex-breakdown and the characteristics of unsteady lift/drag are presented. The effect of pitching movement of the wing on dynamic stall is also studied. |
| Keywords: | transonic flow unsteady flow vortex-breakdown numerical simulation |
