1. 1. 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

3. 2. AERODYNAMIC FORCING & DAMPING COMPUTATIONS IN A TRANSONIC AXIAL TURBINE OF A TURBOCHANRGER USING TIME & FREQUENCY DOMAIN FLOW TRANSFORMATION TECHNIQUES

   University essay from KTH/Energiteknik

   Author : Aravin Dass Naidu; [2016]
   Keywords : ;

   Abstract : The current report discusses efficient and accurate numerical techniques to evaluate aerodynamic disturbance and damping forces based on investigations carried out at ABB Turbo System AG. The test turbomachine comprises a single-stage transonic axial turbine analysed with the fluid dynamic software ANSYS CFX 17.0 and post-processing tool Matlab. READ MORE

4. 3. Influence of Clocking on the Aerodynamic Forcing of 1.5 Stages of a Transonic Compressor

   University essay from KTH/Kraft- och värmeteknologi

   Author : Daniel Villanueva; [2011]
   Keywords : Clocking;

   Abstract : The trend of modern turbomachines towards lighter and slimmer blades exposed to higher loadings has made forced response problems emerge as a major concern in the design process of these machines. Forced response accounts for unsteady forces on the blade due to non-uniformities in the flow field. READ MORE
