  1. 1. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gusten Zandler Andersson; [2023]
    Nyckelord :Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Sammanfattning : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. LÄS MER

  3. 2. Biogasprocessen : Bestämning av verkningsgrad

    M1-uppsats, Akademin för hållbar samhälls- och teknikutveckling

    Författare :Martin Thomassen; [2010]
    Nyckelord :Rötning; förbehandling; uppgradering; metan; substrat; verkningsgrad;

    Sammanfattning : Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. LÄS MER

  4. 3. Black-Box Model Development of the JAS 39 Gripen Fuel Tank Pressurization System : Intended for a Model-Based Diagnosis System

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Vibeke Kensing; [2002]
    Nyckelord :Reglerteknik; system identfication; model-bases diagnosis; Black-Box model; JAS 39 Gripen; fuel system; tank pressurization; Reglerteknik;

    Sammanfattning : The objective with this thesis is to build a Black-Box model of the tank pressurization system in JAS 39 Gripen. This model is intended to be used in an existing diagnosis system for the security control in the tank pressurization system. The tank pressurization system is a MIMO system. LÄS MER

  5. 4. Active Model-based diagnosis -applied on the JAS39 Gripen fuel pressurization system

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Ronny Olsson; [2002]
    Nyckelord :Technology; model-based diagnosis; JAS39 Gripen; fuel pressurization; fault isolation; fault detection; TEKNIKVETENSKAP;

    Sammanfattning : Traditional diagnosis has been performed with hardware redundancy and limit checking. The development of more powerful computers have made a new kind of diagnosis possible. Todays computing power allows models of the system to be run in real time and thus making model-based diagnosis possible. LÄS MER
