  1. 41. Aeroelastic instabilities simulations on turbofan HP compressorblisk at surge-like reversed flow conditions

    University essay from KTH/Flygdynamik

    Author : Raphael Murray; [2013]
    Keywords : ;

    Abstract : This paper presents the work done at the High Pressure Compressor design division of Safran Snecma to simulate the flutter behaviour of a compressor blisk at reversed flow conditions. The report states the preliminary phase of modelling the reversed flow on an entire compressor with a stationary simulation and the single blade aeroelastic study results obtained. READ MORE

  3. 42. Fluttering Analysis in Wind Turbine Blade

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Prabaharan Elangovan; [2012]
    Keywords : Wind turbine blade; Aerodynamic loads; Finite Element Method; Mode shapes; Deformations and ANSYS.;

    Abstract : The wind turbine blades often subjected by a phenomenon fluttering which leads to a structural damage. Therefore, it is necessary for design engineers to predict the fluttering behavior while designing the blades. READ MORE

  4. 43. Parametric Study on the Aeroelastic Stability of Rotor Seals

    University essay from KTH/Kraft- och värmeteknologi

    Author : Qingyuan Zhuang; [2012]
    Keywords : Aeromechanics; turbomachinery; labyrinth seal; flutter; CFD; FEM;

    Abstract : Labyrinth seals are widely used in rotating machinery and have been shown to experience aeroelastic instabilities. The rapid development of computational fluid dynamics now provides a high fidelity approach for predicting the aeroelastic behavior of labyrinth seals in three dimension and exhibits great potential within industrial application, especially during the detailed design stages.

  5. 44. Ventricular fibrillation detection with Neural Networks

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Carl Klinglöf; [2012]
    Keywords : ventricular fibrillation neural network;

    Abstract : A solution to distinguish ventricular fibrillation and ventricular flutter from other arrhythmias and from disturbances caused by body motion or muscle activity with the use of a neural network has been investigated. Ventricular fibrillation and ventricular flutter occurs when the cardiac muscle cells are not triggered by the cardiac conduction system, but rather by ectopic foci preventing a synchronized contraction of the cardiac muscle cells and therefore inhibiting the hearts capability to properly pump blood.

  6. 45. Daped concert hall

    University essay from KTH/Arkitektur

    Author : Mersedeh Madhoush; [2012]
    Keywords : Concert hall; Stockholm; Galärparken; Djurgården; مرسده مدهوش;

    Abstract : Through the development of draping and pleating methods of heavy fabric referring indirectly to the stage Curtain, the aim of the project is to study ambiguous coexistence of masking and exposing made by repetitive folds, simultaneously developing technique studies and site analysis and apply them to make a new concert hall for Stockholm.The thesis defines the concert hall a public space, and further develops the concert hall as a public space by exposing the commonly inaccessible backstage area in on the ground floor Visitors and concert-goers have the opportunity to look behind the scenes and reconsider the value of art by seeing how a piece of music has been shaped and rehearsed.
