  1. 1. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sanger Shinwari; [2023]
    Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

  3. 2. Computational Analysis of Spray Deflector Designs

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Osman Gyokhan Ali; [2023]
    Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. READ MORE

  4. 3. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    University essay from KTH/Teknisk mekanik

    Author : Martina Formichetti; [2022]
    Keywords : Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Abstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE

  5. 4. Aeroengine transients in altitude test facility

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Baptiste VILLENEUVE; [2022]
    Keywords : ;

    Abstract : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. READ MORE

  6. 5. Wading Simulations of Complete Heavy-Duty Vehicles

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emma Samuelsson; Sofie Benzler; [2022]
    Keywords : CFD; Volume of Fluid; Wading; Heavy-Duty Vehicles; STAR-CCM ;

    Abstract : Wading is the phenomenon where a vehicle drives through water with a relatively deep water level. Sincea large portion of the vehicle is submerged in water it can affect the driveability and function of individualcomponents. READ MORE
