Introduction of Passive Shock Control in an Interactive Boundary Layer Methodscid flow/boundary layer interaction model, improved by the introduction of a proper ventilation through the airfoil surface. Concerning the inviscid flow, the Euler model has been considered, while an integral method for the boundary layer has been used for accuracy and computing time reasons.

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.

The contributions, designated Chapters 9 through 23, are assembled in the order of the three tasks which comprise the research program. The sequence of presentation and the main contents of the research performed are briefly given below.

General Properties of Elastic Bodiesthe 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.
