  1. 21. Turbulent Flow in Constricted Blood Vessels : Quantification of Wall Shear Stress Using Large Eddy Simulation

    Författare :Roland Gårdhagen; Matts Karlsson; Toste Länne; Leif Rune Hellevik; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The genesis of atherosclerosis has previously been shown to be affected by the frictional load from the blood on the vessel wall, called the wall shear stress (WSS). Assessment of WSS can therefore provide important information for diagnoses, intervention planning, and follow‐up. LÄS MER

  3. 22. Circular bioeconomy through valorisation of agro-industrial residues by the edible filamentous fungus Neurospora intermedia

    Författare :Rebecca Gmoser; Mohammad J Taherzadeh; José António Teixeira; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neurospora intermedia; mycoprotein; carotenoids; feed; solid-state fermentation; circular bioeconomy; Resource Recovery; Resursåtervinning;

    Sammanfattning : Prevention of dramatic climate change and ensuring food and nutrition security for subsequent generations necessitates the reduction of greenhouse gas emissions and efficient use of the world’s resources, including efficient waste disposal. The agro-industrial sector generates a large amount of organic waste, that is currently underexploited owing to poor waste management practices. LÄS MER

  5. 24. Experimental and Numerical Investigations of Flames Stabilized by Swirl Flow and Bluff-body:Flame Structures and Flame Instabilities

    Författare :Yiheng Tong; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame structures; Flame instabilities; Blowout limits; Flashback; Swirl Flow; Bluff-body; Chemiluminescence; PIV;

    Sammanfattning : Combustion and its control are essential to our existence on this planet since we knew it. Nowadays, the largest share of the world’s electricity and most of our transportation systems are powered by combustion. In addition, industrial processes also rely heavily upon combustion. LÄS MER

  7. 25. Simulation Modelling of a Shift to Service-Based Offerings : Resource efficiency and operational implications in the context of the circular economy

    Författare :Raphael Wasserbaur; Tomohiko Sakao; Erik Sundin; Steve Evans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource efficiency; resource effectiveness; circular economy CE ; sociotechnical systems; systems thinking; simulation; product service system PSS ; system dynamics;

    Sammanfattning : The unsustainable levels of resource use and emissions of our economies and their threat to future generations are core issues of our time. The circular economy (CE) conceptualises a different type of economy that is restorative and regenerative by design and aims to keep products, components and materials at their highest utility and value at all times, distinguishing between technical and biological cycles.
