Dessolin, Joël; Bessière, Emmanuel; Mauss, Jacques Passive laminar drag reduction. (Analyse de la réduction passive de la traînée laminaire.) (French. Abridged English version) Zbl 0935.76022 C. R. Acad. Sci., Paris, Sér. II, Fasc. b, Méc. Phys. Astron. 327, No. 5, 449-456 (1999). Summary: We use a multi-layer model to describe the influence of wall perturbations on the boundary layer flow. The originality of the method lies in the use of non-regular second-order asymptotic expansions arising from the presence of two longitudinal length scales. Using the lower deck canonical problem, we study the influence of wall perturbations on laminar drag reduction.
