Summary
This paper describes a linearized theory of the two- and three-dimensional incompressible viscous flows ensuing from locally unstable velocity profiles. The theory is used to propose a hypothesis for the mechanisms governing formation of the turbulence wedge behind a fixed roughness element.
Résumé
On a présenté une théorie linearizée pour l'évolution des écoulements visqueux, incompressibles, bi-et tri-dimensionels, suivant l'instabilité locale des profils de vitesse de la couche limite laminaire. Utilisant les résultats de la théorie, on a proposé une hypothèse sur les mécanismes qui régissent la formation du “coin de turbulence” en aval d'un élément de rugosité fixée.
