BiGlobal Stability of Shear Flows: Spanwise & Streamwise Analyses

Laminar-turbulent transition dictates an increase in skin friction. The resulting turbulent skin friction contributes to approximately 40% of the total drag of commercial aircraft. Reducing the turbulent flow region by postponing transition can therefore significantly reduce the carbon footprint and costs of flying. Transition prediction is required in order to do so, which depends on a detailed understanding of the transition process
