  1. 1. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads

    University essay from KTH/Energiteknik

    Author : Borbala Bernus; [2020]
    Keywords : LOx; gasification; two-phase CFD simulation; rapid oxidation; rocket; cryogenic; hybrid; atomisation; LOx; förgasning; 2-fas CFD-simulering; snabb oxidation; raket; kryogen; hybrid; atomisering;

    Abstract : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. READ MORE

  3. 2. Experimental Study to Reduce CO Emissions in Skellefteå Kraft's 16 MW Bubbling Fluidized Bed Boiler

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

    Author : William Johansson; [2019]
    Keywords : ;

    Abstract : Skellefteå Kraft has had high CO emissions problems in a bubbling fluidized bed (BFB) boiler in Malå.Statistical emissions data from 2013 to 2019 shows plant average emissions of 1230 ppm. Thisexceeds the recommended 440 ppm (6 % O2) that Naturvårdsverket proposes (Naturvårdsverket,2005). READ MORE

  4. 3. Implementation of continuous filtering frequency comb Vernier spectroscopy for continuous acquisition of spectra in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adam Edlund; [2017]
    Keywords : optical frequency comb; continuous filtering Vernier spectroscopy;

    Abstract : In this project laser absorption spectroscopy was performed on a flame in a Fabry-Pérot cavity, using an optical frequency comb. Optical frequency comb spectroscopy is a technique that allows broadband ultra-sensitive detection of molecular species in gas phase. READ MORE

  5. 4. CFD analysis of nozzle effect on jet formation

    University essay from KTH/Mekanik

    Author : Mustafa GÜDÜCÜ; [2015]
    Keywords : ;

    Abstract : This project is concerned with CFD simulations of jets issued from elliptical nozzles. The investigated jet flow in this project is turbulent flow emanating from microscopic nozzles into a combustion chamber. READ MORE

  6. 5. Prediction of ignition limits with respect to fuel fraction of inert gases. : Evaluation of cost effective CFD-method using cold flow simulations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Johan Sjölander; [2015]
    Keywords : Combustion; gas turbines; CFD;

    Abstract : Improving fuel flexibility for gas turbines is one advantageous property on the market. It may lead to increased feasibility by potential customers and thereby give increased competiveness for production and retail companies of gas turbines such as Siemens Industrial Turbomachinery in Finspång.
