  1. 1. 3D CFD Simulations of Hydrogen Engine Combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hao Liu; [2023]
    Keywords : Technology and Engineering;

    Abstract : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. READ MORE

  3. 2. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johan Samuelsson; [2022]
    Keywords : Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Abstract : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. READ MORE

  4. 3. Parametric Study of Separation in Outlet Diffuser of Rocket Nozzle Cooling Channel Rig : The Effect of Heat Flux and Angle of Outlet Diffuser for Rectangular-to-Circular Cross Section Transitions

    University essay from KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Author : Hector Älfvåg; [2021]
    Keywords : ;

    Abstract : The use of natural gas with high methane content as rocket fuel has gained substantial industrial attention over the past number of years. Several actors including SpaceX and Blue Origin are developing natural gas powered rocket engines. READ MORE

  5. 4. Influence of Reynolds Number and Heat Flux when Cooling an Array of Cylinders

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

    Author : Erik Fagerström; [2020]
    Keywords : Reynolds Number; Heat Flux; Porous Media; Cooling;

    Abstract : When batteries are used, it is of interest to know how high the temperature will become and if the cooling is efficient enough. In this thesis project, the geometry used are batteries placed in an array shape, inside a box. This gives the possibility of assuming porosity conditions when looking at the box from the outside.

  6. 5. Catching Ash : Methodology for ash accumulation in diesel particulate filters

    University essay from KTH/Materialvetenskap

    Author : Charis Pavlou; [2019]
    Keywords : diesel engine; diesel particulate filter; particulate matter; testing rig; accelerating ash accumulation;

    Abstract : The diesel particulate filter captures particulate matter that is produced in the diesel engine. A small fraction of particulate matter is comprised by ash forming matter. When the combustible fraction of particulate matter is removed from the filter, the ash, which is incombustible, remains. READ MORE
