2. 1. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture

   Author : Worrada Nookuea; Jinyue Yan; Hailong Li; Eva Thorin; Bin Liang; Xiaoyan Ji; Jesus Zambrano; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.

4. 2. Friction in highly pressurized lubricants and its relation to thermo-physical properties

   Author : Bert-Olof Åhrström; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : The objective of this work was to increase the understanding of which lubricant properties control transient friction, and during what environmental conditions friction is minimized. The experiments have been conducted during conditions relevant to an elastohydrodynamic contact, with pressures extending up to 2. READ MORE

   Author : Yuting Tan; Per Alvfors; Lars Nord; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 conditioning; CO2 transport; CO2 storage; CO2 mixtures; CO2 cryogenic; heat exchanger; compressor; property impact; viscosity; thermal conductivity; property model; Koldioxidkonditionering; transport koldioxid; koldioxidlagring; koldioxidblandningar; kryogenisk process; värmeväxlare; kompressor; tillståndsstorheters påverkan; viskositet; värmekonduktivitet; tillstånds-storhets¬modell; Chemical Engineering; Kemiteknik;

   Abstract : Carbon capture and storage (CCS) is one of the most promising technologies that may significantly reduce CO2 emissions. A better understanding of the thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. READ MORE

6. 4. Bio-diesel Spray Combustion Modeling Based on a Detailed Chemistry Approach

   Author : Junfeng Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine modeling; bio-diesel; thermo-physical properties; detailed chemistry combustion; emissions formation; spray characteristics;

   Abstract : The increased use of bio-diesel fuel is expected to reduce emissions of carbon-containing greenhouse gases. To optimize the application of bio-diesel in internal combustion engines, a theoretical model has been developed. READ MORE

7. 5. Thermophysical Properties of Aqueous Solutions Used as Secondary Working Fluids

   Author : Åke Melinder; Björn Palm; Antero Aittomäki; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary working fluids; secondary refrigerants; indirect systems; aqueous solutions; ice slurry; thermophysical properties; freezing point; density; viscosity; specific heat; thermal conductivity; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

   Abstract : Secondary working fluids (secondary refrigerants, heat transfer fluids, antifreezes, brines) have long been used in various indirect re-frigeration and heat pump systems. Aqueous solutions (water solu-tions) have long been used as single phase (liquid only) secondary working fluids for cooling in supermarkets, ice rinks, heat recovery systems, heat pumps and other applications.
