  2. 1. Long-Term Simulation of Coastal Evolution

    Author : Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

    Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE

  4. 2. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

    Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; Henrik Saxèn; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural iron ore; iron production; characterization; physical and metallurgical properties; sinter; pellet; direct reduction; low temperature degradation; sample weight; sample positioning; microstructure; reduction degree; solid conversion; Volumetric Model; Grain Model; Random Pore Model; Muko; Uganda;

    Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

  5. 3. Study of the Apparent Kinetics of Biomass Gasification Using High-Temperature Steam

    Author : Aliaksandr Alevanau; Weihong Yang; Wlodzimierz Blasiak; Anna Ponzio; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature gasification; random pore model; grain model; volumetric model; TGA; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

    Abstract : Among the latest achievements in gasification technology, one may list the development of a method to preheat gasification agents using switched ceramic honey combs. The best output from this technology is achieved with use of water steam as a gasification agent, which is heated up to 1600 °C. READ MORE

  6. 4. WC grain growth during sintering of cemented carbides : Experiments and simulations

    Author : Karin Mannesson; John Ågren; Annika Borgenstam; Håkan Engqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; Grain growth; Abnormal grain growth; Image analysis; Modeling; 3-D grain size distribution; Inverse Saltykov; Materials science; Teknisk materialvetenskap;

    Abstract : Cemented carbides are composite materials consisting of a hard carbide and a ductile binder. They are powdermetallurgically manufactured, where liquid-phase sintering is one of the main steps. The most common cemented carbide consists of WC and Co and it is widely used for cutting tools.
