  1. 1. Receptivity of Boundary-Layer Flows over Flat and Curved Walls

    Författare :Lars-Uve Schrader; Luca Brandt; Dan Stefan Henningson; Gregoire Casalis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Boundary-layer receptivity; laminar-turbulent transition; swept-plate boundary layer; Görtler flow; leading-edge effects; swept-wing flow; crossflow vortices; Görtler rolls; disturbance streaks; wall roughness; free-stream turbulence; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Direct numerical simulations of the receptivity and instability of boundary layers on flat and curved surfaces are herein reported. Various flow models are considered with the aim to capture aspects of flows over straight and swept wings such as wall curvature, pressure variations, leading-edge effects, streamline curvature and crossflow.

  4. 3. Advanced surgeries, medicines and materials for corneal regeneration

    Författare :Maria Xeroudaki; Neil Lagali; Beatrice Bourghardt Peebo; Per Fagerholm; Stefan Schrader; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Corneal transplantation is often the only treatment option in cases of corneal blindness, with the main challenges being the scarcity of human donors, risk for graft failure and suboptimal visual outcome due to suture-related issues. Alternative therapies are sought that either address the above transplantation issues directly or stimulate the cornea’s repair mechanism and regenerative properties to restore transparency without the need for transplantation.
