  1. 6. Developing Humidified Gas Turbine Cycles

    Författare :Michael Bartlett; KTH; []
    Nyckelord :advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Sammanfattning : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. LÄS MER

  3. 7. Mechanical Behaviour of Gas Turbine Coatings

    Författare :Mats Eskner; KTH; []
    Nyckelord :thermal barrier coatings; TBC; small punch test; miniaturised disc bending test; mdbt; spherical indentation; gas turbine coatings; NiAl; NiCoCrAlY; NiCrAlY; mechanical properties;

    Sammanfattning : Coatings are frequently applied on gas turbine components inorder to restrict surface degradation such as corrosion andoxidation of the structural material or to thermally insulatethe structural material against the hot environment, therebyincreasing the efficiency of the turbine. However, in order toobtain accurate lifetime expectancies and performance of thecoatings system it is necessary to have a reliableunderstanding of the mechanical properties and failuremechanisms of the coatings.

  4. 8. Design of an Experimental Facility for Investi- gating the Flow in a Low Pressure Turbine Exit Structure

    Författare :Borja Rojo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbine Rear Frame; Turbine Exhaust Case; Experimental; Exit Guide Vane; Engine Exit Structure; Aerodynamics; Outlet Guide Vane; Gas Turbine; Wind Tunnel; Heat transfer.; CFD; Turbine Rear Structure;

    Sammanfattning : This report presents the design of a turbine facility for investigating the flow in the EES located at Chalmers University of Technology. The EES is the structure located downstream of the LPT in a jet engine. In this rig, in order to generate realistic inlet boundary conditions for the EES, an LPT stage is located upstream of the EES.

  5. 9. Engine Optimized Turbine Design

    Författare :Nicholas Anton; Anders Christiansen-Erlandsson; Magnus Genrup; Marc Gugau; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Heavy-duty; Turbine; Axial; Radial; Machine Design; Maskinkonstruktion;

    Sammanfattning : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. LÄS MER

  7. 10. Aerothermal Study of Intermediate Turbine Ducts

    Författare :Martin Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerodynamics; Intermediate Turbine Duct; Gas Turbine; Heat Transfer; Experimental;

    Sammanfattning : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. LÄS MER
