Numerical Investigation of Passive and Active Control of Unsteady Compressible Flow
Abstract
Numerical simulations of flow controls applied to airfoils
undergoing oscillatory motion in compressible flow
are presented. Currently available efficient and accurate
numerical methods for the full compressible flow
equations and advanced turbulence models are used
for the numerical predictions. Time-accurate computations
at low angles of incidence indicate development
of flow unsteadiness for the slatted airfoil. It is
found, however, that the leading-edge slat effectively
suppresses dynamic stall, it improves dynamic blade
response, and reduces flow separation, for compressible
flow speeds. It was also found that dynamic stall
can be suppressed using control with pulsating jets.
