Abstract
Computational simulation of vertical tail buffet in an internal vortex breakdown flow is considered. The fiuid-flow problem is formulated using the full, compressible, unsteady Navier-Stokes equations which are solved using an implicit, flux-difference splitting, finite volume scheme. The fluid-flow problem is solved in a configured circular duct using quasi-axisymmetric assumptions to simplify the flow equations. A plate is placed transverse to the incoming flow. Solution of the flow in the duct is performed with and without a rigid plate, and with and without an elastic plate. The elastic response of the plate is calculated assuming that it is a cantilever beam undergoing bending oscillations. Two material properties are considered. The grid is moved using a simple exponential fit. The fluid, structural, and grid equations are solved sequentially.
The results show the importance of including the effect of the aerodynamic damping in the problem by allowing the sequential interaction of the fluid and structural equations. This simplified model is demonstrated as effective in investigating the problem of vertical tail buffet due to vortex breakdown dominated flows in a configured duct.
