  1. 21. Fundamental studies of non-premixed combustion in turbulent wall jets using direct numerical simulation

    Författare :Zeinab Pouransari; V. Arne Johansson; Christer Fureby; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; non-premixed combustion; global reaction; direct numerical simulation; wall-jet; heat release; mixing scales; heat transfer; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The present thesis deals with the fundamental aspects of turbulent mixingand non-premixed combustion in wall-jet flows. Direct numerical simulations(DNS) of compressible turbulent flows are performed in a wall-jet configura-tion, which has a close resemblance to many industrial combustion applica-tions. LÄS MER

  2. 22. Fast Microwave-Enhanced Intra-, Pseudo-intra- and Intermolecular Heck Reactions

    Författare :Andreas Svennebring; Mats Larhed; Anja Sandström; Erik Van der Eycken; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; palladium; Heck reaction; chelation control; microwave; Farmaceutisk kemi;

    Sammanfattning : The Heck reaction is one of the most appreciated methods for carbon-carbon bond formation. Due to its mildness and ability to be tuned by additives, it often leaves few alternative competitive reactions. It has also proven easy to develop the reaction conditions in an environmentally benign direction. LÄS MER

  3. 23. As simple as ABC - the dd → α X reaction explained

    Författare :Anders Gårdestig; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Strålningsvetenskap; Radiation biology; Strålningsbiologi; kärnfysik; Nuclear Physics;

    Sammanfattning : A model is presented for the dd → αππ reaction. It is based on two parallell and almost independent NN → dπ processes, where the final deutrons fuse to form the α particle. While underestimating the results at lower energies, the modelgives a good quantitative description of the α-particle momentum distributions throughout the 0. LÄS MER

  4. 24. Radiation in simulations of high intensity laser-matter interaction

    Författare :Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma; nonlinear dynamics; particle-in-cell; Manley-Rowe; radiation reaction; synchrotron radiation;

    Sammanfattning : We consider electromagnetic waves propagating in plasmas, with two main themes covered. First nonlinear plasma theory and wave-wave interaction. Here a wave-wave symmetry, the Manley-Rowe relations, is used as a method of determining the physicality of modified plasma fluid equations. LÄS MER

  5. 25. Palladium(II)-Catalyzed Oxidative Carbocyclization/Functionalization of Allenynes

    Författare :Teresa Bartholomeyzik; Jan-Erling Bäckvall; Diego J. Cárdenas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium catalysis; oxidation; carbocyclization; allenynes; boron reagents; kinetics; selectivity; reaction mechanism; organisk kemi; Organic Chemistry;

    Sammanfattning : The selective formation of carbon-carbon bonds constitutes a key transformation in organic synthesis with useful applications in pharmaceutical or material industry. A particularly versatile tool for carbon-carbon as well as carbon-heteroatom bond formation is palladium catalysis, which allows for mild and selective routes even towards complex structures. LÄS MER
