This paper presents a framework for the optimal active separation control mechanism on a realistic high-lift configuration. To control the separation, synthetic jet actuation is applied on the pressure and suction side of a 3D wing with slats, flaps

In this work we introduce a robust and consistent discrete adjoint solver that has been embedded into the open-source multiphysics framework SU\(^2\) by exploitation of the fixed-point structure of the flow solver. At inviscid and turbulent optimizat

Non-Ideal Compressible Fluid-Dynamics (NICFD) has recently been established as a sector of fluid mechanics dealing with the flows of dense vapors, supercritical fluids, and two-phase fluids, whose properties significantly depart from those of the ide

In this paper, we present an unsteady aerodynamic and aeroacoustic optimization framework in which algorithmic differentiation (AD) is applied to the open-source multi-physics solver SU2 to obtain design sensitivities. An AD-based consistent discrete

In this paper, we present a discrete adjoint-based optimization framework to obtain the optimal distribution of the porous material over the trailing edge of a 3-D flat plate. The near-body strength of the noise source generated by the unsteady turbu

The paper describes general methodologies for the solution of design optimization problems. In particular we outline the close relations between a fixed point solver based piggy back approach and a Reduced SQP method in Jacobi and Seidel variants. Th

Discrete Adjoint based Sensitivity Analysis for Optimal Flow Control of a 3D High-Lift Configuration
Publikováno v:
21st AIAA Computational Fluid Dynamics Conference.
Active flow control techniques are used to delay or prevent the turbulent flow separation on the flap of a high-lift configuration. Effective separation control and thus lift enhancement can be achieved by finding the optimal set of actuation paramet
