Prediction and Control of Laminar-turbulent Transition in High-speed Boundary-Layer Flows

Issues related to prediction of laminar-turbulent transition on hypersonic configurations in high-altitude flight are discussed. The laminar flow control strategy and appropriate laminarization methods for high-speed vehicles are reviewed. The paper is aimed to motivate the transition study groups to integrate their knowledge and tools in the rational framework of the amplitude method. This may help to coordinate efforts focused on different aspects of the transition problem and improve our transition-prediction and laminar-flow-control capabilities on a solid physics-based foundation.
