Description and Prediction of Transition in Two-Dimensional, Incompressible Flow,

Abstract

This paper deals with a survey of transition problems in two-dimensional, incompressible flows. The first chapter is devoted to a general description of phenomena leading to turbulence under the influence of various factors: free-stream turbulence, sound, pressure gradient, oscillations of the external flow, roughness, suction, wall curvature. Then, linear and non-linear stability theories are briefly discussed. This chapter ends with a review of results concerning the structure and growth of turbulent spots and the progressive disappearance of intermittency phenomenon when positive pressure gradients are applied. The second chapter describes practical methods for calculating the transition onset as well as the transition region itself. Methods based on linear stability theory, empirical criteria, intermittency methods and turbulence models are presented successively. Some applications of these techniques are also given. (Author)
