  1. 1. Establishing a methodology to investigate factors that affect Tip Leakage Loss : In a small scale Organic Rankine Cycle (ORC) turbine

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Anand Ashok Kaushik; [2022]
    Keywords : Ansys CFX; CFD; ORC; Turbines; Tip leakage; Internal flow; Loss; Entropy; Correlations;

    Abstract : With growing awareness and necessity for the world to move towards more sustainable (energy saving) forms of power generation, focus on the commercial use of Organic Rankine Cycle (ORC) turbine systems has subsequently increased in turn. ORC systems with their modular design can thus help in recovering heat, obtained as a byproduct from a variety of industrial processes, and thereby increase their overall system efficiency.

  3. 2. Numerical Analysis Of 2D And 3D losses In Organic Rankine Cycle Turbine

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Pranav Rane; [2021]
    Keywords : Computaional Fluid Dynamics; CFD; Turbine loss; Profile loss; Tip leakage loss; 2D loss; 3D loss; ANSYS CFX; ANSYS Fluent; Organic Rankine Cycle Turbine; Parametric Study;

    Abstract : World resources are becoming more and more scarce due to the increasing demand. Hence, the industry is moving towards sustainable development in order to suffice the needs of the future generations. Electricity is one such resources that account for 90% of the daily utility. In Sweden alone 378 TWh of electricity is consumed over a year. READ MORE

  4. 3. Influence on tip leakage flow in a compressor cascade with plasma actuation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Haotian Wang; [2019]
    Keywords : Flow control; DBD Plasma actuation; phenomenological model; numerical simulation; tip leakage flow; compressor cascade.; Flödesreglering; DBD Plasma‐aktuator; numerisk simulering; toppspelsflöde; kompressor kaskad.;

    Abstract : As one of the key components of aero engines, compressor is required to endure higher pressure,  possess  higher  efficiency  and  wider  operating  range. Intensive studies have been made on tip leakage flow and researchers find that by reasonably organizing tip leakage flow, aero engines are  more likely to achieve better performance and reliability.

  5. 4. 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

  6. 5. Sensitivity Analysis in 3D Turbine CFD

    University essay from KTH/Mekanik

    Author : Simon Kern; [2017]
    Keywords : ;

    Abstract : A better understanding of turbine performance and its sensitivity to variations in the inletboundary conditions is crucial in the quest of further improving the efficiency of aero engines.Within the research efforts to reach this goal, a high-pressure turbine test rig has been designedby Rolls-Royce Deutschland in cooperation with the Deutsches Zentrum für Luft- und Raumfahrt(DLR), the German Aerospace Center.
