  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. Conjugate Heat Transfer Analysis of HPGP Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done.

  4. 3. Computational Fluid Dynamics and Modeling of a Free Surface Flow

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

    Författare :Mathieu Marmier; [2023]
    Nyckelord :CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER

  5. 4. CFD-modeling of labyrinth weir flood discharge with ice cover

    Master-uppsats, KTH/Betongbyggnad

    Författare :Erik Isberg; [2023]
    Nyckelord :;

    Sammanfattning : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. LÄS MER

  7. 5. Experiments and simulations of gas flow through a NiCd battery

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Sarah Petersson; [2023]
    Nyckelord :NiCd; battery; porous medium; experiment; CFD; NiCd; batteri; poröst medium; experiment; CFD;

    Sammanfattning : This report describes the thesis work carried out regarding experiments and simulations of the gas flow through a NiCd battery. The objective of the work was to investigate how different geometries of the flip top vent on the battery and the level of porosity of the flame arresting disc impacted the amount of potassium carbonate created at the outlet of the vent.
