  1. 1. Characterizing flowability of metal powders

    Kandidat-uppsats, KTH/Materialvetenskap; KTH/Materialvetenskap

    Författare :David Correa Zapisotski; Martin Wallhed; [2019]
    Nyckelord :Powder Metallurgy;

    Sammanfattning : Powder metallurgy is a growing field with much potential. The core purpose and problem in this work is attempting to describe and understand what and how metal powder properties impact powder flowability. LÄS MER

  2. 2. Slope processes and strength of material in silt rich ravines in Säterdalen, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper; Uppsala universitet/Institutionen för geovetenskaper

    Författare :Pontus Westrin; Nils Melin; [2015]
    Nyckelord :Ravine; Silt Ravine; Silt; Cohesion; Shear ring; Shear stress; Angle of repose; LIDAR; Stress; Strength of material; Säterdalen; Raviner; Dalarna; Jord; Silt; Siltravin; Hållfasthet; Kohesion; Lidar;

    Sammanfattning : Slope processes are important to understand if we are to protect fragile environments. Every year slope development in weak soils put nearby infrastructure in risk zones of sliding and ravine erosion takes away field areal from farmers as they grow even larger. LÄS MER

  3. 3. Experimental investigation of the flowability of oxygen carriers for Chemical-Looping Combustion

    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Tobias Herrmann; [2015]
    Nyckelord :Chemical-Looping Combustion; Flowability; Oxygen carrier; Funnel flow;

    Sammanfattning : questrationin an innovative way. Air and fuel are separately handled in two fluidizedbed reactors. Interconnection and reaction are achieved by circulating an oxygencarrier between both reactors. The oxygen carrier is a crucial component, as it isresponsible for the performance of the overall process. LÄS MER
