This paper deals with the practical and theoretical implications of model reduction for aerodynamic flow-based control problems. Various aspects of model reduction are discussed that apply to partial differential equation- (PDE-) based models in gene

A large percentage of the losses in performance and effectiveness of airborne optical systems are caused by turbulence. In an effort to reduce these adverse effects in airborne optical systems, we are exploring the use of both openand closed-loop flo

In this paper, the reactive flow control of delta-wing leading-edge vortices using along-core pulse-widthmodulation flow injection is presented. Leading-edge vortices on the upper surface of a delta wing can augment lift. Manipulating breakdown point

In this paper, we present a finite difference method for the implementation of the rotation of a circular cylinder in the incompressible flow field by solving the two-dimensional unsteady Navier-Stokes equations. The approach is to use staggered grid

A short computational program was undertaken to evaluate the effectiveness of a closed-loop control strategy for the stabilization of an unstable bluff-body flow. In this effort, the non-linear one-dimensional Ginzburg–Landau wake model at 20% abov

An ovel hierarchical modular control methodology using closed-loop flow control for active virtual shaping of aerodynamic surfaces is developed. Through wind tunnel experimentation and numerical simulation, we show that collocated sensor‐actuator p

This paper focuses on two-dimensional incompressible Newtonian fluid flow over a flat plate and studies the problem of reducing the frictional drag exerted on the plate using active feedback control. Several alternative control configurations, includ

This paper treats the question of feedback linearizing control of two-dimensional incompressible, unsteady wake flow. For definiteness, flow past a circular cylinder is considered, but the design approach presented here is applicable to other flow co
