    Abstract : In this energy transition era, turbocharging is still an important technology for the automotive industry to reduce fuel consumption and lower emissions in its vehicles. This importance can be seen from both conventional fossil-fuel powertrains, and emerging applications, such as increased utilization of biofuels along with hydrogen fuel cells. READ MORE

  4. 2. Numerical Methods for Turbomachinery Aeromechanical Predictions

    Author : Maria Angelica Mayorca; Damian Vogt; Torsten Fransson; Robert Kielb; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeromechanics; numerical tools; methods; turbomachinery; aeroelasticity; gas turbines; vibrations;

    Abstract : In both aviation and power generation, gas turbines are used as key components. An important driver of technological advance in gas turbines is the race towards environmentally friendly machines, decreasing the fuel burn, community noise and NOx emissions. READ MORE

  5. 3. The Influence of Flow Leakage Modelling on Turbomachinery Blade Forcing Predictions

    Author : Tobias Gezork; Björn Laumert; Paul Petrie-Repar; Damian Vogt; Mehdi Vahdati; KTH; []
    Keywords : Energiteknik; Energy Technology;

    Abstract : Vibrations in turbomachinery engine components are undesirable as they put the structural integrity of the components at risk and can lead to failure during the lifetime of the turbomachinery engine. Vibrations arising from aerodynamic forces and stability of turbomachinery blades is assessed in the discipline of aeromechanics. READ MORE
