  1. 1. Acoustic source strength determination of turbocharger in an unfavourable acoustic environment

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Balaji Vejendla; [2019]
    Keywords : ;

    Abstract : The aim of the M.Sc thesis work is to specify a measurement method suitable for deter-mining the sound power levels and especially to quantifying the levels at the compressor blade pass frequency of a turbocharger in the new turbo performance rig located at Scania CV AB, Södertälje.

  2. 2. The Danger of Defending the Environment in Developing Countries : A structured focused comparison study of Honduras and El Salvador

    University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Author : Denny Edvinsson; [2019]
    Keywords : Environmentalists; Developing Countries; Deadly Violence; Limited Access Orders; Structured Focused Comparision;

    Abstract : The environment is taking a larger part of the debate resulting in the creation of UN declarations, domestic and regional laws, public pressure on companies and politicians to take responsibility, and a greater awareness on our increasingly exploited planet. However, the people who are affected the most, poor and often indigenous people, find themselves in an increasingly dangerous position when they try to defend the planet. READ MORE

  3. 3. Study of tip clearance flows

    University essay from KTH/Flygdynamik

    Author : Camille Fournis; [2018]
    Keywords : turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

    Abstract : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. READ MORE

  4. 4. Compressor CFD simulation method development : A CFD study

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

    Author : Johan Björk; [2018]
    Keywords : CFD; centrifugal compressor; CFX; CHT; Conjugate Heat Transfer; Surge;

    Abstract : This master thesis project consisted of three parts that all were performed through CFD simulations with the purpose to develop Scania's methods in the subject of CFD. All parts included simulations on Scania's SC92T70 centrifugal compressor. READ MORE

  5. 5. Flow simulations with relevance to a centrifugal compressor and the eect of the inlet geometry

    University essay from KTH/Mekanik

    Author : Ander Eza; [2015]
    Keywords : ;

    Abstract : Turbocharging the internal combustion engine is one of the most effective ways to reduce the fuel consumption and fulll the green house gas emissions requierements. Nevertheless, this techinque has some limitations that need to be addressed in order to improve the turbocharger performance. READ MORE
