  1. 6. Analysis and Design of a Microgravity Drop Tower

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Tristan Edwards; [2023]
    Keywords : drop tower; microgravity;

    Abstract : A drop tower is a device that produces a microgravity environment by allowing an experiment to free fall for a short period of time, usually less than 10 seconds. Certain types of drop towers are also capable of reproducing the gravitational conditions of other celestial bodies, such as Lunar and Martian gravity. READ MORE

  3. 7. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johan Samuelsson; [2022]
    Keywords : Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Abstract : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. READ MORE

  4. 8. Material Characterization and Blade Impact Simulation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Gustaf Bodare; [2022]
    Keywords : Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Abstract : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. READ MORE

  5. 9. Self-consistent dielectric formalism scheme for the paramagnetic electron gas under warm dense matter conditions

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fotios Kalkavouras; [2022]
    Keywords : Warm Dense Matter WDM ; Quantum One-Component plasmas qOCP ; Vashishta-Singwi VS ; Dielectric Formalism;

    Abstract : The present thesis aims to further a somewhat unexplored area of Warm Dense Matter (WDM) physics through the use of tools developed within the dielectric formalism. WDM is an exotic form of matter with densities close to the solid state and temperatures of several eV. READ MORE

  6. 10. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linda Péroux; [2022]
    Keywords : Technology and Engineering;

    Abstract : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. READ MORE
