  2. 1. Heat and Mass Transfer Investigations of Relevance for Food Engineering Applications

    Author : Dirk Sterner; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; mathematical modelling; frozen and non-frozen food; minced beef patties; cooking; heat and mass transfer; plate heat exchangers; evaporation;

    Abstract : This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.

  4. 2. Numerical Modeling of Turbulent Combustion and Flame Spread

    Author : Zhenghua Yan; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Flame Spread; Pyrolysis; Heat Transfer; Radiation; CFD; Turbulent Combustion Modeling; Teknik;

    Abstract : Theoretical models have been developed to address several important aspects of numerical modeling of turbulent combustion and flame spread. The developed models include a pyrolysis model for charring and non-charring solid materials, a fast narrow band radiation property evaluation model (FASTNB) and a turbulence model for buoyant flow and flame.

  5. 3. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

    Author : Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

    Abstract : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. READ MORE

  6. 4. Experimental and numerical evaluation of heat transfer in the press hardening process

    Author : Per Salomonsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : In recent decades, the use of high- and ultra high strength steels in modern car bodies has increased drastically. This is due to both severe legislation of passenger passive safety and the recent year's effort to reduce fuel consumption to decrease environmental harmful emissions. READ MORE

  7. 5. Heat Transfer Prediction of In Service Welding in a Forced Flow of Fluid

    Author : Per Lindström; Lars-Erik Svensson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sjöfartsvetenskap; Maritime Science;

    Abstract : An algorithm for heat transfer prediction of in-service welding operations in a forcedflow of fluid is presented. The algorithm presented is derived from Rosenthal’s 3D heatflow equation and boundary layer approximations. READ MORE
