  5. 3. Aerodynamic Investigations of a High Pressure Turbine Vane with Leading Edge Contouring at Endwall in a Transonic Annular Sector Cascade

    Author : Ranjan Saha; Torsten Fransson; Markus Jöcker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high pressure turbine; secondary flow; leading edge contouring; endwall; experimental investigations; losses; flow field; hub cooling flow; högtrycksturbinen sekundärströmning; framkantsmodifiering; ändvägg; experimentell undersökning; förluster; strömningsfält; filmkylning av inre platform;

    Abstract : Efficiency improvement is an important aspect to reduce the use of fossil-based fuel in order to achieve a sustainable future. Gas turbines are mainly fossil-fuel based turbomachines, and, therefore, efficiency improvement is still the subject of many on-going research activities in the gas turbine community. READ MORE

  6. 4. Investigations of Heat Transfer and Fluid Flow in the Pocket Region of a Gas Turbine Engine and Cooling of a Turbine Blade
