  1. 1. Improving the understanding of photoelectron currents on Solar Orbiter : Utilizing theory and empirical measurements

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Melker Marminge; [2023]
    Keywords : Solar Orbiter; Photoelectric Currents; Photoelectric Effect; Thermal Bending; Outgassing; Thermionic Emission; Numerical Approximation; Physical Modeling;

    Abstract : Spacecraft experience electric currents on conductive materials exposed to sunlight, which introduces noise in scientific data. These currents are mainly due to the photoelectric effect and should therefore be proportional to the inverse square heliocentric distance. READ MORE

  3. 2. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Jijesh Rajan; [2022]
    Keywords : Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Abstract : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. READ MORE

  4. 3. Aspects of gating system improvement in a cast iron foundry

    University essay from KTH/Materialvetenskap

    Author : Fahami Annan Green; Felix Göttfert; [2021]
    Keywords : Gating system; Cast iron; Foundry; Pouring basin; Offset step basin; Sprue; Ingjutssystem; Gjutjärn; Gjuteri; Gjutskål; Förskjuten steggjutskål; Nedlopp;

    Abstract : The gating system transfers the iron melt from the ladle to the void in the casting mould. The gating systems dimensions and designs are crucial for the success of a casting and a poor gating system is a leading cause of scraps. READ MORE

  5. 4. Parametric Study of Separation in Outlet Diffuser of Rocket Nozzle Cooling Channel Rig : The Effect of Heat Flux and Angle of Outlet Diffuser for Rectangular-to-Circular Cross Section Transitions

    University essay from KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Author : Hector Älfvåg; [2021]
    Keywords : ;

    Abstract : The use of natural gas with high methane content as rocket fuel has gained substantial industrial attention over the past number of years. Several actors including SpaceX and Blue Origin are developing natural gas powered rocket engines. READ MORE

  6. 5. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

    University essay from Mälardalens högskola/Framtidens energi

    Author : Emil Skoglund; [2021]
    Keywords : PEFC; PEM; convection; mass transport; heat transport; co-flow; temperature profile; heat transfer model; transient; steady state; water concentration profile; water vapor profile; relative humidity; through-plane cross section;

    Abstract : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. READ MORE
