Numerical study of jet perforated boundaries in the flow over the profile NaCa-0012

A new method for wall interference reduction is considered it is a combination of perforated wall and a controlled boundary layer. The numerical simulation is performed to study the efficiency of this concept by using the well-known model of the airfoil NACA- 0012. Analysis of the results makes it possible to draw a number of conclusions as to a possibility to reduce the interference of flow boundaries and choose the optimal combinations of parameters characterizing these boundaries.
