  1. 6. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

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

    Author : Viktor Lange; [2023]
    Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

  3. 7. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    University essay from KTH/Kraft- och värmeteknologi

    Author : David Fredouelle; [2023]
    Keywords : Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Abstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions.

  4. 8. Evaluating the feasibility of chitosan as an adhesive for wood laminates and as a matrix for transparent wood

    University essay from KTH/Fiber- och polymerteknologi

    Author : Nihar Sakhadeo; [2023]
    Keywords : Transparent wood; Chitosan; Biobased adhesives; Biopolymers; Laminate; Transparent trä; Kitosan; Biobaserad adhesiv; Biopolymer; Laminat;

    Abstract : En av grundpelarna i alla hållbara system är införandet av en cirkulär ekonomi, som främjar återanvändning och återvinning av material. Plast är en av i utmaning i detta avseende på grund av den stora produktionsvolymen variation i sorter och långsamma nedbrytn. READ MORE

  5. 9. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Dominika Kiesling; [2023]
    Keywords : oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Abstract : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.

  6. 10. Utilization of Biomethane in Decarbonising India´s Energy Mix

    University essay from KTH/Energiteknik

    Author : Niraj Ravindra Kunkulol; [2023]
    Keywords : Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

    Abstract : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. READ MORE
