  2. 1. Hydrodynamics and Heat Transfer in Vertical Falling Films with Smooth and Modified Heat-Transfer Surfaces – An Experimental and Numerical Investigation

    Author : Anders Åkesjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film thickness; local heat transfer coefficient; numerical simulations; heat transfer; falling film; VOF; evaporation.;

    Abstract : High energy utilization efficiency is important to achieve a sustainable society. By having highly efficient heat exchangers, more energy can be recovered and reused at a lower cost. READ MORE

  4. 2. Radiative Heat Transfer in Suspension-Fired Systems

    Author : Adrian Gunnarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-firing; rotary kiln; combustion; Radiative heat transfer; soot volume fraction;

    Abstract : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. READ MORE

  5. 3. Packed-Fluidized Bed Reactors – Batch Experiments and Fundamental Modeling with Random Metal Packings

    Author : Nasrin Nemati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bubbling fluidized bed; Heat transfer; Confined fluidization; Chemical-looping combustion; Mass transfer; Random packing; Packed-fluidized bed;

    Abstract : The aim of this work is to investigate the effect of random packings on heat and mass transfer phenomena, when applied in bubbling fluidized beds. For this purpose, first, the heat transfer coefficient to a horizontal tube submerged in a fluidized bed containing various types of random packings was investigated. READ MORE

  6. 4. Reduction of heat transfer and heat load in internal combustion engines

    Author : Joop Somhorst; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; TBC; thermal barrier coating; surface roughness; engine; heat transfer; emissions; alumina; zirconia;

    Abstract : Thermal insulation of the combustion chamber in an engine has great potential to reduce fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. READ MORE

  7. 5. Computational discovery of antibiotic resistance genes and their horizontal transfer

    Author : David Lund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phylogenetic analysis; Antibiotic resistance; horizontal gene transfer; computational screening;

    Abstract : Antibiotic resistance is increasing among clinical infections and represents one of the most serious threats to public health. Pathogens often become resistant by acquiring mobile antibiotic resistance genes (ARGs) via horizontal gene transfer (HGT). READ MORE
