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.
