1. 1. Turbulence Intensity Measurements in a High-Pressure Gas Turbine Stage

   University essay from KTH/Kraft- och värmeteknologi

   Author : Ettore Scami; [2022]
   Keywords : Turbulence Intensity; turbine; stage efficiency; grid; turbomachinery; length scales;

   Abstract : This Thesis work focused on the acquisition and evaluation of data on mean velocity, turbulence intensity and length scales obtained via hot wire measurements in a high pressure single-stage land-based turbine available at the Department of Heat and Power Technology in KTH. Turbulence was generated by the use of grids and twoprobes, upstream and downstream of the turbine stage, were used. READ MORE

3. 2. Turbo For Fuel Cell Electric Vehicle

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Adam Hansson; Mohammed Abu Al-Soud; [2022]
   Keywords : Turbo; Fuel Cell; Centrifugal Compressor; Radial Turbine; Axial Turbine; Technology and Engineering;

   Abstract : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. READ MORE

4. 3. Aerodynamic studies of the flutter behavior of a compressor jet engine : Establishment of 1D criteria for the appearance of flutter within low pressure compressors

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

   Author : Lucas Citoleux; [2022]
   Keywords : ;

   Abstract : Turbojet compressors are subject to numerous vibration phenomena that limit their good operability. Among these different phenomena, flutter is a major concern during the study and design phase. This aeroelastic instability can have an impact on the correct operation of the compressor. READ MORE

5. 4. Development of a Tool for Inverse Aerodynamic Design and Optimisation of Turbomachinery Aerofoils

   University essay from KTH/Flygdynamik

   Author : Berkin Kurtulus; [2021]
   Keywords : Aerodynamics; Turbomachinery Airfoil design; Inverse Design Automation; Airfoil Optimization;

   Abstract : The automation of airfoil design process is an ongoing effort within the field of turbo-machinery design, with significant focus on developing new reliable and consistent methods that can meet the needs of the engineers. A wide variety of approaches has been in use for inverse airfoil design process which benefit from theoretical inverse design, statistical methods, empirical discoveries and many other ways to solve the design problem.
