1. 6. Undertray Design and Development Procedure with CFD : An Optimization Study of Different UndertrayDesigns with CFD Computations

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Aaron Poutiainen; [2021]
   Keywords : ;

   Abstract : Race car aerodynamics has played a vital part to improve lap times over the years of motor racing. Having good road adhesion with slick tires and aerodynamic downforce will increase the vehicles maximum lateral force and thus higher cornering speeds can be achieved. READ MORE

3. 7. Learning to Fly: Upgraded Aerodynamics and Control Surfaces

   University essay from KTH/Flygdynamik

   Author : David Jacobsson; [2021]
   Keywords : Hybrid; UAV; Reinforcement Learning; Machine Learning; Controller; Flight Controller; Control Theory; Learning to Fly; Aerodynamics; Hybrid; UAV; Drönare; Flygmekanik; Reglerteknik; Maskininlärning; Regulatordesign;

   Abstract : In recent times the unmanned quadcopter aircraft has been used for a widening range of applications, but for longer distances it still falls short of conventional airplanes in terms of energy usage. There exists hybrid configurations of unmanned aircraft which combine the mobility of quadcopters and the range of fixed-wing aircraft. READ MORE

4. 8. Time-Resolved Adaptive Finite Element Simulations for Building Aerodynamics : A proof of concept on minimal computational resources

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

   Author : Linde van Beers; [2021]
   Keywords : Building aerodynamics; Computational fluid dynamics; Wind engineering; FEniCS; Adaptive mesh refinement; Atmospheric boundary layer; Direct finite element simulation; Byggnadsaerodynamik; Beräkningsströmningsdynamik; Vindteknik; FEniCS; Adaptiv nätförfining; Atmosfäriskt gränsskikt; Direkt finita elementsimulering;

   Abstract : The effect of building geometry on the wind environment of cities is such that it can cause problems like wind danger, discomfort and poor ventilation of airborne pollutants. Computational fluid dynamics (CFD) can play a role in assessing changes in wind environment caused by building projects before realisation at little cost. READ MORE

5. 9. Design of a drone system for maritime search and rescue missions

   University essay from KTH/Flygdynamik

   Author : Emil Pettersson; [2020]
   Keywords : Sea Rescue; Drone; Flying Wing; Blended Wing Body; SAR; Tailless; BWB; XFLR5; Search and Rescue; Drönare; Flygande Vinge; Sjöräddning; Eftersök; XFLR5;

   Abstract : The work summarized in this report aims to investigate how a drone airplane design can be optimized to create a safer and more efficient sea rescue by providing staff with an early picture, performing search missions and aiding communication through visual contact. A flying wing is in theory one of the most efficient designs for a fixed wing aircraft, at the same time as it also offers high structural efficiency for its given size. READ MORE

6. 10. A study on Friction Boundary Conditions with Unicorn/FEniCS-HPC

   University essay from KTH/Numerisk analys, NA

   Author : Irene Natale; [2019]
   Keywords : ;

   Abstract : The aim of this thesis is to present and validate a boundary condition formulation for CFD problems that includes a friction parameter. In the first part of the thesis the incompressible Navier-Stokes system of equations and the friction boundary conditions are presented. READ MORE
