  1. 16. Numerical approach of a hybrid rocket engine behaviour : Modelling the liquid oxidizer injection using a Lagrangian solver

    University essay from KTH/Mekanik

    Author : Gustave Sporschill; [2017]
    Keywords : Hybrid propulsion; combustion; numerical simulations; two-phase flow; La-grangian approach;

    Abstract : To access and operate in space, a wide range of propulsion systems has been developed, from high-thrust chemical propulsion to low-thrust electrical propulsion, and new kind of systems are considered, such as solar sails and nuclear propulsion. Recently, interest in hybrid rocket engines has been renewed due to their attractive features (safe, cheap, flexible) and they are now investigated and developed by research laboratories such as ONERA.

    Abstract : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies.

  4. 18. Immersed Cooling of Electronics

    University essay from KTH/Energiteknik

    Author : Axel Nord; Zhao Yiqing; [2016]
    Keywords : ;

    Abstract : This master thesis is supported by Ericsson to conduct research on immersed liquid cooling of electronics. By this technology, the liquid will be in direct contact with the electronics. The research begins with investigations in industrial background, literature review and theory in heat transfer.

  5. 19. Development of the endurance test program and the assembly fixture for TRITON11™

    University essay from Lunds universitet/Innovation

    Author : William Lundström; [2016]
    Keywords : Nuclear fuel; Boiling Water Reactor; fretting wear; test program; assembly fixture; Technology and Engineering;

    Abstract : The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. READ MORE

  6. 20. A CFD Method for Simulation of Gas-Liquid Flow in Cooling Systems : An Eulerian-Eulerian Approach

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Malin Lind; Karl Johan Josefsson; [2016]
    Keywords : CFD; Gas-Liquid; Two-phase; Eulerian; Air bubbles; Flow; Eulerian-Eulerian; Cooling system;

    Abstract : When designing modern engines it is important to construct a cooling system that cools the engine structure efficiently. Within the cooling system there is always a certain amount of air which can accumulate and form air pockets in critical areas, such as the water jacket, which can lead to wall degradation. READ MORE
