  1. 1. Conjugate Heat Transfer Analysis of HPGP Thruster

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Lisa Svensson; [2024]
    Keywords : aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Abstract : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. READ MORE

  3. 2. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Kreshnik Margaritari; [2023]
    Keywords : Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Abstract : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  4. 3. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Tanmmay Rout; [2023]
    Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  5. 4. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nadja Rabizadeh; [2023]
    Keywords : CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Abstract : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. READ MORE

  6. 5. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

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

    Author : Siddharth Suresh Sumathi; [2023]
    Keywords : Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Abstract : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. READ MORE
