1. 1. Bending the Curve – the Role and Interplay of Municipal Energy Planning and Municipal Spatial Planning for Climate Change Mitigation in Sweden

   Författare :Vincent Wretling; Berit Balfors; Ulrika Gunnarsson-Östling; Christina Hörnberg; Catalina Turcu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local energy and climate planning; municipal comprehensive planning; wind power planning; climate policy integration; Strategic Environmental Assessment; institutional capacity building; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : The global climate is changing rapidly, which pronounces the need for imminently bending the curve of greenhouse gases emissions. The local authorities have been recognised as key actors in this decarbonisation, due to their wide-ranging responsibilities, including different mandates for local planning. LÄS MER

3. 2. Electrostatic Interactions in Complex Liquids : A Thermodynamic Analysis Based on the Poisson-Boltzmann Equation and the Flexible Surface Model

   Författare :Ingemar Carlsson; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AOT; AerosolOT; ionic surfactant; spontaneous curvature; bending modulus; bending energy; Helfrich curvature energy; fluid membrane; complex liquid; flexible surface model; micelle; counterion; Poisson-Boltzmann equation; cell model; L3 phase; sponge phas; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : The aim of this study was to analyse physico-chemical properties of some complex liquids using the Poisson-Boltzmann (PB) cell model; to extend the theory to cover bilayer systems with complex global geometry; finally to apply this new extended model to such bilayer systems. The PB cell model provides a practical tool to examine counterion association and phase behaviour for structures of simple geometries; cylindrical and spherical. LÄS MER

4. 3. Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade

   Författare :Nenad Glodic; Damian Vogt; Matthew Montgomery; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; aeroelastic response; combined modes; bending-torsion flutter; mode superposition; aerodynamic asymmetries; ROM; probabilistic analysis;

   Sammanfattning : Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. LÄS MER

5. 4. Energy Savings by Using Daylight for Basic Urban Shapes : With a Case Study of Three Different Street Types

   Författare :Bengt Sundborg; Tigran Haas; Jan Ejhed; Ulf Ranhagen; Barbara Matusiak; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; daylight; energy; climate; urban design principles; urban pattern; street grid; Arkitektur; Architecture;

   Sammanfattning : During winter the sun is in short supply. But research at KTH shows that solar radiation can be facilitated while energy consumption for lighting is reduced. This provided that the buildings are appropriately designed. But, unfortunately, the sunlight is often not taken into account and the results are the opposite. LÄS MER

7. 5. Numerical Simulation of Unsteady Flows of Physiological Relevance

   Författare :Philip Evegren; Institutionen för energivetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wall shear stress; Biofluid mechanics; Pulsatile flow; Atherosclerosis; Flow in bifurcations;

   Sammanfattning : Pulsatile flows in geometries of physiological relevance have been investigated. Atherosclerotic plaques are (initiated) near junctions and bifurcations in larger arteries. The flow in these regions is characterized by flow separation and unsteadiness, which indicates that local flow conditions contribute to atherogenesis. LÄS MER
