1. 1. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

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

   Author : Arjun Monga; [2023]
   Keywords : coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

   Abstract : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. READ MORE

3. 2. Simulation of Combustion in a Hybrid Rocket Engine

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Oscar Andersson; [2023]
   Keywords : Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

   Abstract : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. READ MORE

4. 3. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances

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

   Author : Johan Germundsson; [2023]
   Keywords : master thesis; cam phaser; simulation; 1D-simulation; GT-SUITE; GT-ISE; Gamma Technologies; oil aeration; oscillations; heavy-duty; engine; phaser; cam torque; stability; cam phaser system; Scania; Scalia CV;

   Abstract : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. READ MORE

5. 4. Design of a modular small-scale PMMA/Air hybrid rocket research engine

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Gustaf von Platen; [2023]
   Keywords : hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

   Abstract : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.

6. 5. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

   University essay from KTH/Kraft- och värmeteknologi

   Author : Birgir Steinn Hermannsson; [2022]
   Keywords : ;

   Abstract : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. READ MORE
