2. 1. Impact of Icing on Wind Turbines Aerodynamic

   Author : Narges Tabatabaei; Michel Cervantes; Barakos George N.; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Wind energy covered 11.6% of Europe electricity demand in 2017. Region with cold climates represent a strong potential for wind energy companies because of their sparse population and proper wind conditions. The global wind energy installations in cold climate regions is forecasted to reach a capacity of 186 GW by the end of 2020. READ MORE

4. 2. The One-Dimensional Turbulence Model Applied to Spray Atomization

   Author : Amirreza Movaghar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Primary breakup; Turbulence; One Dimensional Turbulence ODT ;

   Abstract : Numerical simulation of the spray behavior is an important part of engine research and is critical for combustion optimization. Successful implementation of the advanced modeling tools for sprays is strongly dependent on our current understanding of the physical processes involved. READ MORE

5. 3. Inflation Mechanics of Hyperelastic Membranes

   Author : Amit Patil; Anders Eriksson; Arne Nordmark; Reijo Kouhia; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Mechanics; Inflation; Adhesive Contact; Instabilities; Bifurcation; Limit Point; Teknisk mekanik; Engineering Mechanics;

   Abstract : The applications of inflatable membrane structures are increasing rapidly in the various fields of engineering and science. The geometric, material, force and contact non-linearities complicate this subject further, which in turn increases the demand for computationally efficient methods and interpretations of counter-intuitive behaviors noted by the  scientific community.

6. 4. Towards Automation of Non-Destructive Testing of Welds

   Author : Patrik Broberg; Mikael Sjödahl; Anna Runnemalm; Torbjörn Löfqvist; Högskolan Väst; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; non-destructive testing; NDT; Industriell arbetsvetenskap; Industrial engineering; Experimental Mechanics;

   Abstract : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

7. 5. The Mirroring Immersed Boundary Method - Modeling Fluids with Moving and Interacting Bodies

   Author : Andreas Mark; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; DNS; Fluid-structure interaction; Mirroring immersed boundary method;

   Abstract : The detailed fluid flow around arbitrary, moving, interacting and deforming bodies is both complex and poorly understood and the commercial simulation tools simulating such flows are computationally to demanding. Hence, a new fast and accurate method for simulating complex multi-body flows is required. READ MORE
