  1. 1. Stability and Receptivity of Three-Dimensional Boundary Layers

    University dissertation from Stockholm : KTH

    Author : David Tempelmann; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional boundary layers; parabolised stability equations; adjoint PSE; crossflow instability; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Abstract : The stability and the receptivity of three-dimensional flat plate boundary layers is studied employing parabolised stability equations. These allow for computationally efficient parametric studies. Two different sets of equations are used. READ MORE

  2. 2. Receptivity of crossflow-dominated boundary layers

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : David Tempelmann; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; three-dimensional boundary layers; optimal growth; adjoint solutions; swept wing;

    Abstract : This thesis deals with receptivity mechanisms of three-dimensional, crossflow-dominated boundary layers. The receptivity of two model problems, a swept-flat-plate and a swept-wing boundary layer, is investigated by solving the parabolised stability equations (PSE) as well as by performing direct numerical simulations (DNS).

  3. 3. Optimal Design of Natural and Hybrid Laminar Flow Control on Wings

    University dissertation from Stockholm : Mekanik

    Author : Jan Oscar Pralits; KTH.; [2003]
    Keywords : Fluid; Mathematics; Aeronautics; Optimization;

    Abstract : Methods for optimal design of different means of control aredeveloped in this thesis. The main purpose is to maintain thelaminar flow on wings at a chord Reynolds number beyond what isusually transitional or turbulent. READ MORE
