1. 1. In-situ testing of floating thermal piles in soft sensitive clay

   Författare :Anders Bergström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintained; Cyclic Thermal loading; Energy piles; Field Test; Thermal Piles;

   Sammanfattning : Thermal piles are structural piles with additional function of working as geothermal heat exchangers towards the soil volume. Heating and cooling process of soft soils is known to affect the stress state and soil structure, with potential consolidation settlements and creep as undesired consequences. LÄS MER

3. 2. Mitigating Off-Gassing and Self-Heating in Fuel Wood Pellets Storage : A Raw Materials Selection and Pre-Treatment Centred Approach

   Författare :Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Mani Sudhagar; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid biofuels; densified biomass; heat generation; off-gas emissions; carbon monoxide; carbon dioxide; methane; fatty and resin acids; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : Wood pellets have become a preferred solid biomass fuel for heat and power generation due to their standardized nature, known properties, and consistent quality. However, pellets produced from fresh sawdust sometimes undergo self-heating and off-gassing during storage. This poses a challenge for their transportation and storage. LÄS MER

4. 3. Microcalorimetry and Infrared Spectroscopy : Thermal processes related to solid waste, ageing rubber, phase change materials, and biomass gasification

   Författare :Mohit Pushp; Mikael S. Hedenqvist; Anders Lönnermark; Lars Wadsö; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Microcalorimetry (MC) is a unique technique for an online measurement of heat production. It can be applied to solids, liquids, or gases. MC can be used to measure the heat involved in either exothermic or endothermic processes. LÄS MER

5. 4. Urban Snowmelt Processes: Modelling and Observation

   Författare :Annette Semadeni Davies; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; energy; runoff; snow properties; heterogeneity; hydrological modelling; Urbanisation; snowmelt; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Sammanfattning : In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. LÄS MER

7. 5. Design fires in underground hard rock mines

   Författare :Rickard Hansen; Haukur Ingason; Håkan Frantzich; Mälardalens högskola; []
   Nyckelord :Design fire; underground; hard rock mine; vehicle fire; smoke spread; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : During several decades considerable research activities have been conducted with respect to fires in coal mines, but the research activities with respect to hard rock mines have been limited. As the hard rock mines are getting more complex the need for deeper understanding of fires in underground hard rock mines are getting more in demand. LÄS MER
