  1. 1. CFD investigation of Plate Channels

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Anton Johannesson; [2022]
    Keywords : Plate Heat Exchanger; Turbulence modelling; Generalized k-omega; GEKO; CFD; Computational Fluid Dynamics; Technology and Engineering;

    Abstract : Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. READ MORE

  3. 2. QUANTIFYING ERRORS IN PITCH ANGLE POSITION USING BEM THEORY

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sai Varun Kollappillai Murugan; [2021]
    Keywords : NREL; Qblade; SCADA; Pitch angle errors; Wind turbines;

    Abstract : The wind industry is always seeking ways to better understand the performance of a wind turbine and improve its efficiency. During the operation phase and maintenance, wind turbines go through regular optimization. Due to the regular change in wind speed and direction, wind turbines need to be regulated and positioned accordingly. READ MORE

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

  5. 4. 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

  6. 5. Numerical simulation and experimental validation of a manufactured wing profile

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Niklas Olsson; Christian Selberg; [2019]
    Keywords : Flow; surface roughness; airfoil;

    Abstract : The background for this thesis originates from a study of the flow characteristics for an airfoil of the type NACA0018. The aim for this thesis was to evaluate how the characteristics of the flow over the NACA0018 profile depend on surface roughness. READ MORE
