  1. 1. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction

    University essay from KTH/Teknisk mekanik

    Author : Giacomo Semprini Cesari; [2023]
    Keywords : Active flow control; drag reduction; numerical simulations; turbulent boundary layer; wings;

    Abstract : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. READ MORE

  3. 2. Simulation based optimizing of fog mesh structures for enhanced fog collection

    University essay from KTH/Teknisk mekanik

    Author : Jiawei Miao; [2022]
    Keywords : ;

    Abstract : Water scarcity has been an increasing problem in many places around the world. According to the World Resources Institute, in 2019 nearly 2.6 billion people which takes a third of the world's population live in the area with 'high water scarcity', with 1.7 billion people in 17 countries living under 'extreme water scarcity'.

  4. 3. Explainable Reinforcement Learning for Gameplay

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Àlex Costa Sánchez; [2022]
    Keywords : Explainable Artificial Intelligence; Local Interpretable Model-agnostic Explanations; Reinforcement Learning; Shapley Additive Explanations; Intel·ligencia Artificial Interpretable; Explicacions model-agnòstiques localment interpretables; Aprenentatge per reforç; Explicacions additives de Shapley; Förklarbar artificiell intelligent; Lokala tolkningsbara modellagnostiska förklaringar; Förstärkningsinlärning; Shapleys additiv förklaringar;

    Abstract : State-of-the-art Machine Learning (ML) algorithms show impressive results for a myriad of applications. However, they operate as a sort of a black box: the decisions taken are not human-understandable. READ MORE

  5. 4. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

    University essay from KTH/Teknisk mekanik

    Author : Nikolaos Bozikis; [2022]
    Keywords : Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

    Abstract : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. READ MORE

  6. 5. Convection in a spherical shell under rapid rotation: numerical simulations

    University essay from KTH/Teknisk mekanik

    Author : Camille Rambert; [2022]
    Keywords : convection; rapid rotation; spectral methods; spherical geometry;

    Abstract : A numerical method for solving the buoyancy-driven magneto-convection equations in a rapidly rotating spherical shell is presented. The method is implemented through a FORTRAN 90 program, based on a FORTRAN 66 code written by Hollerbach [International Journal for Numerical Methods in Fluids, 32 (2000)] and partially translated in FORTRAN 90 by Riquier.
