  1. 1. Heat and Mass Transfer in Impingement Cooking. Aspects of Food Quality

    Detta är en avhandling från Chalmers University of Technology

    Författare :Urban Wählby; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; food quality; impingement; cooking; heat transfer; mass transfer; meat; buns;

    Sammanfattning : Hot air impingement is a special form of forced convection, where the air is focused through the use of nozzles at a surface. In combination with rather high air velocities, a jet like phenomenon can evolve, which when used in for example cooking can achieve high heat transfer capacities. An Impingement oven prototype was constructed. LÄS MER

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

    Detta är en avhandling från Mrs Gunvi Andersson, Div. Heat Transfer, Box 118, 22100 Lund, Sweden

    Författare :Dirk Sterner; Lunds universitet.; Lund University.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Termisk teknik; termodynamik; mathematical modelling; frozen and non-frozen food; minced beef patties; cooking; heat and mass transfer; plate heat exchangers; evaporation;

    Sammanfattning : 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. 4. Heat and Mass Transfer to a Single Particle in Fluidized Bed

    Detta är en avhandling från Chalmers University of Technology

    Författare :Gennadij I. Palconok; Chalmers tekniska högskola.; Chalmers University of Technology.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; heat; mass transfer; bubbling; circulating fluidized beds; active particle; turbulence; combustion; devolatilization;

    Sammanfattning : Heat and mass transfer to/from a single active particle in bubbling and circulating fluidized beds have been studied with application to fluidized bed combustion. A method of calculation of the heat and mass transfer coefficients in a bubbling fluidized bed (BFB) has been developed. LÄS MER

  5. 5. Catalytic Converters for Automotive Exhaust Applications. Flow Dynamics, Mass Transfer and Optimization

    Detta är en avhandling från Chalmers University of Technology

    Författare :Fredrik Ekström; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; CFD; catalytic converter; catalysis; pressure drop; TWC; exhaust; flow distribution; mass transfer; entrance effects; pulsations; laboratory reactors; optimization;

    Sammanfattning : In order to reduce emissions from vehicles powered by an internal combustion engine, an exhaust aftertreatment system is normally mounted on the engine. This aftertreatment system normally consists of one or several catalytic converters. LÄS MER
