2. 1. Precision cooling for C02 reduction

   Author : Sudharsan Vasudevan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semi- mechanistic models; internal combustion engine; coolant jacket; active nucleation site density; boiling regimes; subcooled flow boiling;

   Abstract : Global climate is adversely affected by increasing emissions of carbon dioxide and other green-house gases. The road transport sector contributes significantly to these emissions. READ MORE

   Author : Meisam Farzaneh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidization; Fuel mixing; Eulerian-Eulerian; Particle Image Velocimetry PIV ; Numerical Simulation; Eulerian-Lagrangian;

   Abstract : Fluidized bed technology has been commercially applied over severaldecades. However there is still a lack of knowledge that can provide adetailed understanding of the combustion process in fluidized-bed furnaces. READ MORE

5. 3. Phase-field modeling of stress-induced precipitation and kinetics in engineering metals

   Author : Claudio F. Nigro; Christina Bjerkén; Ylva Mellbin; Pär A T Olsson; Reinhart Pippan; Malmö universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-field theory; finite element method; corrosion; finite volume method; phase transformation; hydride; hydrogen embrittlement; linear elastic fracture mechanics;

   Abstract : The formation of brittle compounds in metals operating in corrosive environments can be a tremendous source of embrittlement for industrial structures and such phenomenon is commonly enhanced in presence of stresses. To study this type of microstructural change modeling is preferred to experiment to reduce costs and prevent undesirable environmental impacts. READ MORE

6. 4. Macroscale Modelling of 3D-Woven Composites: Inelasticity, Progressive Damage and Final Failure

   Author : Carolyn Oddy; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D-woven composites; Anisotropy; Damage; Inelasticity; Phase-field; Failure;

   Abstract : Composites with 3D-woven reinforcement have been slowly making their way into different industrial applications. The interlacement of yarns, not only in-plane but also through-thickness, means that in many applications 3D-woven composites can outperform their laminated counterparts. READ MORE

7. 5. Multiscale Modelling of Reinforced Concrete Structures

   Author : Adam Sciegaj; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; reinforced concrete; computational homogenisation; bond-slip; multiscale;

   Abstract : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.
