  1. 1. Relating gas turbine performance to combined cycle efficiency

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Simon Frick; [2018]
    Keywords : combined cycle efficiency; second law efficiency; exergy; HRSG; irreversibility; heat engine; thermodynamics; T-q diagram; Technology and Engineering;

    Abstract : The gas turbine has been around for over a century, providing power for a variety of applications. The efficiency, i.e. the amount of power produced per kilogram of fuel provided, has increased steadily over the years and is today greater than 44 percent in a state of the art gas turbine.

  3. 2. Turbo Heat Transfer Modeling for Control

    University essay from Linköpings universitet/Fordonssystem

    Author : Anon Nordlöf; John Lundqvist; [2018]
    Keywords : Turbo; Control; Heat; transfer; Volvo; Liu;

    Abstract : The demand for lower emission engines forces the car industry to build moreefficient engines. Turbocharged engines are on the rise, and better understandingof the heat transfer and efficiency of the turbocharger is needed to build better ones. READ MORE

  4. 3. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

    University essay from KTH/Mekanik

    Author : Emelie Trigell; [2018]
    Keywords : after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

    Abstract : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. READ MORE

  5. 4. Effects of Non Ideal Inlet and Outlet Pipes on Measured Compressor Efficiency

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Kristoffer Ekberg; [2015]
    Keywords : Turbocharger; Compressor; Thermodynamic; Pipe; Efficiency;

    Abstract : The thesis is about investigating the inlet and outlet pipes effect on the compressors measured performance. From measurements made in a gas stand, a thermodynamic model is to be created and the compressor efficiency further investigated. READ MORE

  6. 5. How to handle boil-off gases from LNG trucks

    University essay from Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Tekniska fakulteten

    Author : Linda Gunnarsson; Erik Helander; [2015]
    Keywords : LNG; Liquefied natural gas; boil-off; boil-off gases; BOG; natural gas;

    Abstract : This master thesis project aims to investigate the circumstances of boil-off for heavy vehicle transports, using LNG as fuel, and suggest possible ways of handling these gases otherwise released into the atmosphere. LNG, Liquefied Natural Gas, is when natural gas is cooled below its vaporisation point, turning it into liquid phase which is a much more dense way of storing and transporting the fuel. READ MORE
