Abstract

The equations of an incompressible, steady bidimensional laminar boundary layer are dealt with in the form of Von Mises variables and are controlled by wall suction or blowing. The cost function is minimized by using the algorithm of steepest descent. The calculation of the gradient of the cost function is carried out by introducing an adjoint state and using a finite difference scheme. A finite element technique, to solve the same equations, is also outlined and a comparison between finite difference and finite element numerical solutions is presented for one pressure gradient flow with wall suction. Some preliminary results of the optimal control are also pointed out.
