2. 21. Determination of Material Properties for Fire Modelling

   Author : Ulf Göransson; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material properties; Material degradation; Measurements; Fire test data; Byggnadsteknik; Building construction; Teknik; Technological sciences; Fire; Surface temperature; Mathematical modelling;

   Abstract : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. READ MORE

5. 23. Thermal response test : method development and evaluation

   Author : Signhild Gehlin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

6. 24. Quantitative image analysis : a focus on automated characterization of structures in optical microscopy of iron ore pellets

   Author : Frida Nellros; Carolina Wählby; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Abstract : Sintering occurs in many types of material such as iron, ceramics and snow, typically during thermal treatment, and aects the material properties, particularly the strength, by the bonding of particles into a coherent structure. In order to improve the mechanical strength in magnetite iron ore pellets it is important to be able to characterize and quantitatively measure the degree of sintering and features that impact the process of sintering.

7. 25. Integrating Latent Heat Storage into Residential Heating Systems : A study from material and component characterization to system analysis

   Author : Tianhao Xu; Samer Sawalha; Björn Palm; Justin NingWei Chiu; Tianshu GE; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase change material; thermal energy storage; heat pump; load shifting; space heating; Energy Technology; Energiteknik;

   Abstract : Latent heat thermal energy storage (LHTES) systems can be coupled with heat pump (HP) systems to realize heat load shifting on demand side. With phase change material (PCM), well designed LHTES components exhibit high storage energy density and thus have large potentials to be integrated in residence where a compact energy storage solution is needed.
