Description and prediction of transition in two-dimensional, incompressible flow
Abstract
Transition problems in two dimensional, incompressible flows were surveyed. The phenomena which lead to turbulence under the influence of various factors are described: free stream turbulence, sound, pressure gradient, oscillations of the external flow, roughness, suction, wall curvature. Linear and nonlinear stability theories are discussed. Results of the application of the structure and to the growth of turbulent spots and the progressive disappearance of intermittency phenomenon are reviewed. Practical methods for calculating the transition onset and the transition region itself are described. Methods based on linear stability theory, empirical criteria, intermittency methods and turbulence models are presented.
