  2. 16. Numerical modelling of fluid flow and particle transport in rough rock fracture during shear

    Author : Tomofumi Koyama; Lahru Jing; Auli Niemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single rock fracture; coupled stress-flow test; shear displacement; fluid flow; particle; Geoengineering; Geoteknik;

    Abstract : The effects of different shearing processes and sample sizes on the fluid flow anisotropy and its impact on particle transport process in rough rock fractures are significant factors that need to be considered in the performance and safety assessments of underground nuclear waste repositories. The subjects, however, have not been adequately investigated previously in either laboratory experiments or numerical modeling. READ MORE

  4. 17. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    Author : Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

  5. 18. Operando Single Particle Catalysis - Combining a Nanoreactor and Plasmonic Nanospectroscopy

    Author : David Albinsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanofluidics; single particle catalysis; Cu oxidation; CO oxidation; dark field scattering spectroscopy; LSPR; microreactor; nanoreactor; heterogeneous catalysis; plasmonic sensing;

    Abstract : Heterogeneous catalysis is an important cornerstone of modern society with strong ties to the development of sustainable sources of energy and products. Catalysts are typically realized as supported metal nanoparticles that offer active sites that can accelerate chemical reactions by providing energetically more favorable reaction paths. READ MORE

  6. 19. Transition in Particle-laden Flows

    Author : Joy Klinkenberg; Luca Brandt; Shuisheng He; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; multi-phase flow; particle-laden; heavy particles; light particles;

    Abstract : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. READ MORE

  7. 20. Heat Transfer in Circulating Fluidized Bed Boilers

    Author : Claes Breitholtz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; similarity; char; heat transfer; tube wall; circulating fluidized bed; particle; radiation; scaling; particle convection; gas convection;

    Abstract : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. READ MORE
