  1. 1. Simulation of Colorless Distributed Combustion

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Hampus Olsson; [2019]
    Keywords : Computational Fluid Dynamics; Combustion; Gas Turbine; Emission reduction; Flameless Combustion; Colorless Distributed Combustion; Technology and Engineering;

    Abstract : Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases.

  2. 2. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

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

    Author : Marko Tošić; [2019]
    Keywords : ;

    Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE

  3. 3. Comparing a full scale test with FDS, FireFOAM, McCaffrey & Eurocode

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Erik Edin; Mattias Ström; [2019]
    Keywords : FDS; FireFOAM; OpenFOAM; Performance-Based Design; Localized fire.;

    Abstract : In the rapidly growing field of CFD-calculations (Computational Fluid Dynamics), companies and organizations are bringing forth new tools, tools that display an image of a given fire scenario. These tools are developed because they provide time efficiency as well as a sustainable economic approach. READ MORE

  4. 4. Machine Learning for Air Flow Characterization : An application of Theory-Guided Data Science for Air Fow characterization in an Industrial Foundry

    University essay from Karlstads universitet

    Author : Robin Lundström; [2019]
    Keywords : Machine learning; ML; Echo State Map; ESM; Echo State Network; ESN; Gaussian Process; GP; Computational Fluid Dynamics; CFD; Theory-Guided Data Science; TGDS; Physics-Guided Data Science; Data science; Cross-discipline; Hybrid model; MatLab; Maskininlärning; ML; Echo State Map; ESM; Echo State Network; ESN; Gaussiska Processer; GP; Beräkningsströmningsdynamik; CFD; MatLab;

    Abstract : In industrial environments, operators are exposed to polluted air which after constant exposure can cause irreversible lethal diseases such as lung cancer. The current air monitoring techniques are carried out sparely in either a single day annually or at few measurement positions for a few days. READ MORE

  5. 5. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Hanna Marklund; [2019]
    Keywords : Supersonic retro propulsion; SRP; Mars; Human mission; Inflatable heat shield;

    Abstract : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. READ MORE
