  1. 31. Investigation Of Scalloping Effects Of Radial Turbines With Computational Fluid Dynamics

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Anders Jacobsson; [2016]
    Keywords : Radial turbine; scallop; inertia; turbocharger; STAR-CCM ; CFD; Technology and Engineering;

    Abstract : Turbochargers should both have high efficiency and rapid engine response. By removing material from the rotating parts in the turbocharger, decreases the inertia. Most suited is the turbine in the turbocharger, which has high density because of nickel-based alloys. READ MORE

  2. 32. Experimental loss measurements in an annular sector cascade at supersonic exit velocities

    University essay from KTH/Kraft- och värmeteknologi

    Author : László Lilienberg; [2016]
    Keywords : Gas trubine; nozzle guide vane; annular sector cascade; secondary flow; efficiency; loss measurements; supersonic exit velocities;

    Abstract : Efficiency improvement is one of the most important aspects of engineering and especially important in the field of energy production. In the past decades, energy was mostly produced by fossil based technologies involving turbomachines, and the efficiency of these machines nearly quadrupled since the introduction of the first economically viable gas turbines.

  3. 33. Hydrostatic transmission in wind turbines : Development of test platform

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Joel Rapp; Jonatan Turesson; [2015]
    Keywords : Wind turbine; Hydrostatic transmission; Test platform; Maximum power tracking; Hydraulic system;

    Abstract : This master thesis project is a part of a larger project with the goal of develop-ing a drivetrain, utilizing a hydrostatic transmission, for horizontal axis mid-sizewind turbines. Some of the benefits from using a hydrostatic transmission are thata variable speed operation is possible without the use of a frequency converter,the generator may be placed on the ground and thus reduce weight in the nacelleand also using hydraulic components can increase lifetime and robustness of thesystem.

  4. 34. Aerodynamic Loss Co-Relations and Flow- Field Investigations of a Transonic Film- Cooled Nozzle Guide Vane

    University essay from KTH/Kraft- och värmeteknologi

    Author : Pak Wing Leung; [2015]
    Keywords : gas turbine; aerodynamics; secondary flow; external cooling; film cooling; aerodynamic loss; high pressure turbine; nozzle guide vane;

    Abstract : Over the last two decades, most developed countries have reached a consensus that greener energy production is necessary for the world, due to the climate changes and limited fossil fuel resources. More efficient turbine is desirable and can be archived by higher turbine-inlet temperature (TIT). READ MORE

  5. 35. Numerical Simulation of Compressible Multicomponent Flows

    University essay from KTH/Mekanik

    Author : Anthony Bourbi; [2015]
    Keywords : ;

    Abstract : France is a country where the sector of energy has a big importance. Seven out of the fourteen companies of the CAC40 (a french stock market index of the 40 biggest companies) are strongly involved in the energy sector: Total, GDF Suez, EDF, Legrand, Schneider Electric, Alstom, and Technip. This industry was also responsible for 1. READ MORE
