1. 1. Forced response numerical investigation of a transonic compressor rotor

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

   Author : Mariana Pires Gonçalves Toco Dias; [2023]
   Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

   Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

3. 2. Fretting fatigue life analysis for a gas turbine compressor blade-disk material combination

   University essay from KTH/Hållfasthetslära

   Author : Elham Khoramzad; [2020]
   Keywords : ;

   Abstract : In order to analyse fretting fatigue life of dove-tail joints used in the compressor stage of a gas turbine, experimental study of different material combinations was conducted using rectangular fatigue specimen and bridge type pads. Specimen and pad interaction was simulated numerically and obtained results was used as input for 2 different crack propagation life prediction methods. READ MORE

4. 3. Modelling and Simulation of Fan Performance using CFD Group

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Shreyasu Subramanya; [2020]
   Keywords : CFD; Centrifugal compressor; Vacuum;

   Abstract : Performance of vacuum cleaners are affected by factors such static pressure, airflow rate and efficiency. In this thesis work, attempt has been made to design a fan to meet the requirements of suction static pressure and air flow rate and in the process understand the fan design parameters that affect these performance parameters.

5. 4. Acoustic source strength determination of turbocharger in an unfavourable acoustic environment

   University essay from KTH/MWL Marcus Wallenberg Laboratoriet

   Author : Balaji Vejendla; [2019]
   Keywords : ;

   Abstract : The aim of the M.Sc thesis work is to specify a measurement method suitable for deter-mining the sound power levels and especially to quantifying the levels at the compressor blade pass frequency of a turbocharger in the new turbo performance rig located at Scania CV AB, Södertälje.

6. 5. RANS & WMLES Simulations of Compressor Corner Separation

   University essay from KTH/Mekanik

   Author : Arthur Poulain; [2019]
   Keywords : Corner Separation; Compressor Linear Cascade; RANS; Wall-Modeled LES; Boundary Layer; Anisotropy; Hörnseparation; Kompressor Linjär Kaskad; RANS; Vägg-Modell LES; Gränsskikt; Anisotropi;

   Abstract : In axial compressor, corner separation phenomenon can occur between the blade surface and the hub. This leads to high total pressure losses, blockage and may worsen to surge. Various studies on NACA65-009 blade were previously performed experimentally and numerically to predict the corner separation. READ MORE
