  1. 1. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jaka Perovšek; [2018]
    Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

    Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE

  2. 2. Study of a Body Subjected to a Vertical Drop into Water – Experiment and Simulations

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

    Author : Josefin Andersson; Monika Englund; [2018]
    Keywords : ;

    Abstract : In computational fluid dynamics (CFD), the computational domain can be discretized using mesh- based methods or particle based methods. During this project; a CFD method that uses smoothed particle hydrodynamics (SPH), in which the computational domain is discretized by particles, is modelled and compared to mesh-based CFD methods, in which the domains are broken into a set of discrete volumes.

  3. 3. Sensitivity Analysis in 3D Turbine CFD

    University essay from KTH/Mekanik

    Author : Simon Kern; [2017]
    Keywords : ;

    Abstract : A better understanding of turbine performance and its sensitivity to variations in the inletboundary conditions is crucial in the quest of further improving the efficiency of aero engines.Within the research efforts to reach this goal, a high-pressure turbine test rig has been designedby Rolls-Royce Deutschland in cooperation with the Deutsches Zentrum für Luft- und Raumfahrt(DLR), the German Aerospace Center.

  4. 4. CFD Investigation of Fluidic Momentum Injection as Alternative to Mechanical High Lift Devices for Boundary Layer Control

    University essay from KTH/Aerodynamik

    Author : Kyle Smith; [2014]
    Keywords : ;

    Abstract : Syftet med detta projekt i aerodynamik ar att prova en metod för kontroll av gränsskiktets beteende med luftinsprutning. En modern vingprofil vid transsonisk hastighet används, som liknar de som finns på de festa kommersiella flygplan. READ MORE

  5. 5. Computational fluid dynamics (CFD) study of co-firing of coal and pretreated biomass

    University essay from KTH/Energi- och ugnsteknik

    Author : A S M Abdul Hye; [2014]
    Keywords : Computation fluid dynamics; co-firing; emission; boiler; coal; biomass; torrefied biomass;

    Abstract : This master thesis describes the co-firing concept, benefits and opportunities of pretreated biomass in pulverized coal boilers for industrial use. Burning fossil fuels, i.e. coal is under immense political pressure as European Union (EU) and other countries are trying to bring down the CO2 emission. READ MORE
