    Numerical Solution of Optimal Control Problems Governed by the Compressible Navier-Stokes Equations

    Theoretical and practical issues arising in optimal boundary control of the unsteady two-dimensional compressible Navier-Stokes equations are discussed. Assuming a sufficiently smooth state, formal adjoint and...

    Evaluation of Adjoint Based Methods for the Prediction of Receptivity

    This paper explores the use of nonparallel adjoint methods to predict the receptivity of two and three-dimensional boundary layers. Solutions obtained from both adjoint Navier—Stokes (ANS) and adjoint paraboli...

    On the Use of LES with a Dynamic Subgrid-Scale Model for Optimal Control of Wall Bounded Turbulence

    This paper presents techniques for optimal control of turbulent flows based on the dynamic subgrid-scale LES model. This control scheme has been implemented using a finite time-window approach where the flow s...
