  4. 33. An aeroelastic prediction model for slender wings in supersonic flow

    University essay from KTH/Flygdynamik

    Author : Zakarias Priebe; Alexander Hasp Frank; [2021]
    Keywords : ;

    Abstract : Aeroelasticity is a multidisciplinary subject encompassing several fields of study. Aeroelastic behaviour is defined by the relation between inertial-, elastic- and aerodynamic forces that appear in dynamic systems in steady- or unsteady conditions. READ MORE

  5. 34. Deep learning for non-intrusive sensing in turbulence with passive scalars

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Arivazhagan Geetha Balasubramanian; [2021]
    Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

    Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

  6. 35. Water quality and organic matter linkages in waters draining arable fields

    University essay from SLU/Dept. of Soil and Environment

    Author : Adam Eriksson; [2021]
