Control of velocity profils by walls deformation in a deformed conduit

Starting from a study of perturbation equations for stationary Newtonian fluid flow in deformed axisymmetric tubes, we propose a semi-analytical method allowing to generate in a given section of the conduit, an arbitrary velocity profil previously defined. We get this velocity profile by geometrical modification of the duct walls on a given length. Doing this, we create a specific perturbation of the upstream profile wich allow., to generate the chosen velocity profile. To cite this article: M. Sijelmassi, J. Khalid Naciri, C. R.
