Abstract: The Lecture Series starts with a comprehensive review of the various paths to transition in wall boundary layers, from the traditional views to the more recent ones. Linear stability analysis is then described in detail. Experiments on boundary layer stability, both in 2-D and 3-D cases are commented, highlighting basic rules, techniques and good practice, including considerations about receptivity, flight experiments and experiments in quiet hypersonic tunnels. Parabolized stability equations are presented, including verification and validation. Direct Navier-Stokes simulations and transition for 2-D flows are then discussed. The recent approaches on transient growth, which can be a significant factor in by-pass transition, are also reviewed, including the cases of 3-D and of supersonic flows. On the practical side, transition prediction methods for subsonic, transonic, supersonic and hypersonic flows are reviewed. Control of transition by heating, cooling, is discussed, as well as design for natural laminar flow, laminar flow control, or hybrid laminar flow control. Specific subjects like attachment line instability and surface imperfection problems are also considered, and the role of chemical reactions in the case of hypersonic flows.
