An Investigation of Passive Control Applied to Swept Shock-Wave / Boundary-Layer Interactionsthe effects of passive control. The numerical investigation was also performed using a three-dimensional Navier-Stokes code modelling the wall mass flow through the porous plate with a new empirical relationship. Good agreement was found between the experimental and numerical data with and without passive control.

Extension, Validation and Application of the DA VII Transonic Airfoil Code with Passive Shock Controlayer interaction with grid adaptation. The numerical results are in agreement with the experimental data concerning the wave drag reduction but also the viscous drag increase. In addition, the SC code has been applied for a parametric study of the main passive SC design parameters to support the design of the DA LVA-1A model for passive SC.

Development of Viscous-Inviscid Interaction Codes for Prediction of Shock Boundary-Layer Interactiongrid refinement, but one contains simpler inviscid equations in unsteady flow..Drag reduction seems possible in steady flow, but is rather exceptional. Unsteady flows, together with buffet damping by passive control, have been computed.

Airfoil Tests with and without Control (Task 3), in addition, have smaller margins as far as drag-rise and buffet boundaries are concerned when compared to turbulent designs. During the course of the investigation, having perused early results, it was agreed that DLR would retest the original airfoil VA-2 which had demonstrated the benefits of passive control [1.3].

Shock Boundary Layer Interaction Control Predictions using a Viscous-Inviscid Interaction Procedure he “passive” control of shock boundary layer interaction, where part of the solid surface of the airfoil is replaced by a porous surface over a shallow cavity, has been investigated with regard to improving the aerodynamic characteristics of supercritical airfoils.
