The Prediction of Laminar-Turbulent flow over wings and airfoils is necessary for low-Reynolds number airflows. The Prediction of onset of transition based on linear and Parabolized Stability Equations (PSE) using en method is reviewed and factors that influence the choice of approach are discussed. Comparison between prediction of linear and parabolized stability equation are given for a range of flow conditions on an Infinite sweptback wing.

A non-parallel linear stability analysis which utilizes the assumptions made in the parabolized stability equations is applied to the buoyancy-driven flow in a differentially heated cavity. Numerical integration of the complete Navier–Stokes and energy equations is used to validate the non-parallel theory by introducing an oscillatory heat input at the upstream end of the boundary layer. In this way the stability properties are obtained by analysing the evolution of the resulting disturbances. The solutions show that the spatial growth rate and wavenumber are highly dependent on the transverse location and the disturbance flow quantity under consideration. The local solution to the parabolized stability equations accurately predicts the wave properties observed in the direct simulation whereas conventional parallel stability analysis overpredicts the spatial amplification and the wavenumber.
