1. Numerical Investigation of Various Modelling Strategies for Throttling a Transonic Compressor Rig Diffuser
University essay from KTH/Kraft- och värmeteknologiAbstract : The concern of this study is modeling of the flow field in the diffuser of a 1.5 stage compressor test rig in which the mass flow is constrained at the exit of the diffuser. Constraining method is is applied through, throttling by means of a slab at the exit of the diffuser, where the flow enters the exit volute. READ MORE

2. Numerical analysis of aerodynamic damping in a transonic compressor
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.

3. Determination of aerodynamic damping at high reduced frequencies
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Forced response which is blade vibration due to an external excitation can lead to blade failure. The estimation of the level of vibration is dependent on the determination of aerodynamic damping. This thesisinvestigates the determination of aerodynamic damping at high reduced frequencies in turbomachines. READ MORE
