   Abstract : Innovative methods for providing sustainable heating and cooling through thermal energy storage (TES) have gained increasing attention as heating and cooling demands in the built environment continue to climb. As energy prices continue to soar and systems reach their maximal capacity, there is an urgent need for alternatives to alleviate peak energy use. READ MORE

5. 23. Wood-fibre composites : Stress transfer and hygroexpansion

   Author : Karin M. Almgren; Kristofer Gamstedt; Véronique Michaud; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : Wood fibres is a type of natural fibres suitable for composite applications. The abundance of wood in Swedish forests makes wood-fibre composites a new and interesting application for the Swedish pulp and paper industry. READ MORE

6. 24. Sustainable Implementation of Electrified Roads : Structural and Material Analyses

   Author : Feng Chen; Niki Kringos; Andreas Loizos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrified road; Structural performance; Constitutive modelling; Asphalt; Dielectric loss.; Elektrifierade vägar; Strukturellt beteende; Konstruktivt modellerande; Asfalt; Dielektrisk förlust.; Byggvetenskap; Civil and Architectural Engineering; Transportvetenskap; Transport Science;

   Abstract : Given the promise of the Inductive Power Transfer (IPT) technology for eRoad applications, the potential challenges for a successful integration of dynamic IPT technology into the physical road structure are explored extensively in this research work. The Finite Element Method (FEM) is selected for studying the structural performance of an eRoad under operational conditions. READ MORE

7. 25. Mathematical modelling of fluid flow and heat transfer in steel ladles

   Author : Pan Yuhua; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : In this thesis work, three mathematical models, each of which is suitable for simulating a particular process in the operation of steel ladles, have been developed. Firstly, by using a finite-difference mathematical method (FDM), a one-dimensional numerical model for calculating heat transfer through ladle wall, bottom and top slag layer was established.
