  1. 1. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

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

    Author : Jennifer Ly; [2023]
    Keywords : Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

    Abstract : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.

  4. 3. Demand Side FLexibility and Bidding Strategies for Flexible Loads in Air-Conditioned Buildings

    University essay from KTH/Energiteknik

    Author : Christian Utama; [2020]
    Keywords : ;

    Abstract : Demand-side flexibility (DSF) has been touted as a possible solution to thechallenges in power system operation arising as a result of the increasing intermittent renewables penetration and the emergence of electric vehicles (EVs). In Singapore, where around 24 to 60% of electricity demand in buildings couldbe attributed to heating, ventilation, and air conditioning (HVAC) purposes, air-conditioned building present a potentially major flexibility resource which could be used to provide DSF and help accommodate these challenges.

  5. 4. Cooling storage for 5G EDGE data center

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

    Author : Jennifer Johansson; [2020]
    Keywords : Energy; Data center; Free cooling; 5G;

    Abstract : Data centers requires a lot of energy due to that data centers count as the buildings also contains servers, cooling equipment, IT-equipment and power equipment. As the cooling solution for many data centers around the world right now, the compressor-based cooling solution counts for around 40% of the total energy consumption. READ MORE

  6. 5. Relation Between the Material in Press Hardening Dies and Fully Martensitic Transformation : Sheet properties of thick 3D-sheets in small series production

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jesper Christensson; [2020]
    Keywords : hot stamping; press hardening; material properties;

    Abstract : This report evaluates the influence of the die material on the cooling rate and martensitic transformation of press hardened sheets. The goal was to increase the thicknesses of sheets that can form fully martensitic microstructure when press hardened. READ MORE
