Through research studies conducted over the years, it has been demonstrated that suction is a highly effective active flow control (AFC) technique exploited for laminar-turbulent transition delaying. The primary aim of employing active flow techniques for transition control is the maintenance of laminar flow over a region whose extension needs to be maximized. Considering that half of the total drag stems from skin friction(Marec, J. P., 2001, Drag reduction: a major task for research.), this strategy diminishes the overall friction drag experienced by an object immersed in a fluid. This thesis focuses on utilizing a numerical framework to determine the optimal suction configuration, intending to maximize the extension of the laminar region within a steady, incompressible, and two-dimensional flat plate boundary layer.The computational approach involves integrating the boundary layer equations using an internally developed code (IBL), with suction effects introduced through the wall boundary condition.
