  1. 1. Wall-Resolved and Wall-Modelled LES for a NACA4412 Wing Profile in OpenFOAM

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nikolaos Charisoudis; [2024]
    Nyckelord :;

    Sammanfattning : The purpose of this study is to perform computational fluid dynamics (CFD) simulationfor an incompressible flow around an airfoil and investigate the aerodynamicproperties for different Reynolds numbers (400, 000 and 1, 000, 000) based on the chordlength, at the moderate angle of attack (AoA) of 5o . For this purpose a detailedevaluation of wall-resolved and wall-modelled large-eddy simulations (LES) wereconducted for the NACA4412 wing profile. LÄS MER

  3. 2. Methods and Purposes of Aerodynamic Correlation in Formula Student

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Alix Le Bastard; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.

  4. 3. Range impact of a high velocity aft-propeller on a subsonic aerodynamic body

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jens Teodor Mattsson; [2023]
    Nyckelord :propeller; transsonic; fluid dynamics; cfd;

    Sammanfattning : This master’s thesis is aimed to examine the possible range increase of a ballistically fying body equipped with a propeller working at transonic velocities. To determine whetherthe propeller will provide an improvement in range, results from simulations are compared to corresponding cases of similar bodies fying without a propeller. LÄS MER

  5. 4. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Alexander Elliott Meyer Ströborg; [2022]
    Nyckelord :low Reynolds number; reflex airfoils; CFD; XFOIL;

    Sammanfattning : Low Reynolds number airfoil analysis has become increasingly significant as urban air mobility vehicles and unmanned aerial vehicles surge in popularity. The Green Raven project at KTH Aero aims to use reflex airfoils where little data is available beyond classical analysis. LÄS MER

  7. 5. CFD investigation of Plate Channels

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

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

    Sammanfattning : 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. LÄS MER
