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

    Master-uppsats, KTH/Kraft- och värmeteknologi

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

    Sammanfattning : 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. LÄS MER

  3. 2. Technical performance modelling and optimization of PVT collectors in GSHP integration

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marin Courcault; [2023]
    Nyckelord :PVT; ISO9806:2017; mass flow; use conditions; test conditions; coefficients optimization; TRNSYS; PVT; ISO9806:2017; massflöde; användningsförhållanden; testförhållanden; optimering av koefficienter; TRNSYS;

    Sammanfattning : In order to contribute to reducing the CO2 emissions related to heating in housing buildings, PVT+GSHP systems appear to be interesting solutions and therefore need to be further investigated to optimise their design and increase their deployment on the field. This thesis focused on building PVT model, using the ISO9806:2017, to be integrated in a PVT+GSHP model and determining optimal PVT design parameters for this system. LÄS MER

  4. 3. Radar Based Solutions for Crushing andScreening Applications

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Emma Ehrlin; [2022]
    Nyckelord :Millimeter-wave radar; material mo Kalman filter; mass flow; volume flow; scanning; distance measurements; conveyor belt; Millimeter-wave radar; Kalman filter; massflöde; volymflöde; distansmätingar; transportband;

    Sammanfattning : This project was carried out for a Company in the mining and construction business, and focused on the development of a radar based material monitoring solution for conveyor belts. A minor prestudy showed that there are possible customer values related to material monitoring solutions for equipment relevant for the Company, and that such solutions using radar possibly can fulfil the application requirements.

  5. 4. Utvärdering av en ny torkningsteknik för diskmaskiner : En parameterstudie som utvärderar torkprocessen i en diskmaskin integrerat med värmepumpsteknologin

    Master-uppsats, Karlstads universitet

    Författare :Adam Ståhlberg; [2022]
    Nyckelord :Energibehov; Torkningsgrad; Torktumlare; Fuktig luft;

    Sammanfattning : Denna studie har undersökt en torkningsprocess för diskmaskiner där värmepumpsteknologin appliceras. I och med den nya energimärkningen som implementerades för vitvaror under 2021, har detta inneburit hårdare krav på energianvändningen för diskmaskinsindustrin. Torktumlare har tidigare genomgått samma problematik som diskmaskinerna. LÄS MER

  7. 5. Investigation on Operation of the Compact Molten Salt Reactor by Modelling the Primary Circuit in GeN-FOAM

    Master-uppsats, KTH/Fysik

    Författare :Jelle Oving; [2022]
    Nyckelord :molten salt reactor; GeN-Foam; delayed neutrons; OpenFOAM; multi-physics; smältsaltreaktor; GeN-Foam; fördröjda neutroner; OpenFOAM; multifysik;

    Sammanfattning : In recent years there has been a revision of the molten salt nuclear reactor concept for production of power. Moving of fissile material throughout the primary circuit for these types of reactors creates the necessity of novel physics solvers to study movement of delayed neutron precursors, plant operation, accident scenario's; crucial for design.
