  1. 1. X-ray-induced intermolecular reactions in mixed clusters

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Astrid Bergman; [2022]
    Keywords : molecular cluster; biophysics; X-ray;

    Abstract : The aim of this project was to study what mixed cluster fragments were formed in the interaction between radiation and H2O-CO2 clusters formed by adiabatic expansion, both experimentally and using simulations. The experiment was done using a mass spectrometer at the MAX IV synchrotron facility and by studying the time-of-flight of the ionic fragments. READ MORE

  4. 3. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Oskar Darselius Berg; [2020]
    Keywords : Technology and Engineering;

    Abstract : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. READ MORE

  5. 4. CFD Investigation of Aerodynamic Drag Reduction for an Unloaded Timber Truck

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Raffaele Colombi; [2018]
    Keywords : CFD; Aerodynamics; Drag Coefficient; Truck;

    Abstract : The road transport industry is facing a strong need for fuel consumption reduction, driven by the necessity of decreasing polluting emissions, such as CO2 and NOX, as well as coping with strict regulations and increasing fuel costs. For road vehicles the aerodynamic drag constitutes a major source of energy consumption, and for this reason improving the aerodynamic performance of the vehicle is an established approach for reducing fuel consumption and greenhouse gases emissions.

  6. 5. 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
