  3. 2. Feedback and adjoint based control of boundary layer flows

    Författare :Mattias Chevalier; Dan Henningson; Jean-Marc Chomaz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; fluid and plasma; mechanical engineering; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Linear and nonlinear optimal control have been investigated in transitional channel and boundary layer .ows. The flow phenomena that we study are governed by the incompressible Navier–Stokes equations and the main aim with the control is to prevent transition from laminar to turbulent flows. LÄS MER
