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

    Författare :Urban Wählby; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cooking; impingement; meat; mass transfer; buns; food quality; heat transfer;

    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 to a Single Particle in Fluidized Bed

    Detta är en avhandling från Stockholm : Mekanik

    Författare :Gennadij I. Palconok; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transfer; turbulence; circulating fluidized beds; active particle; bubbling; heat; 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

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

    Detta är en avhandling från Stockholm : Mekanik

    Författare :Fredrik Ekström; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TWC; optimization; exhaust; laboratory reactors; catalytic converter; catalysis; pressure drop; entrance effects; CFD; mass transfer; pulsations; flow distribution;

    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

  5. 5. Fluid dynamics and mass transfer in bubble columns with and without packing

    Detta är en avhandling från Stockholm : Mekanik

    Författare :Peter Therning; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; packed bubble column; fluid dynamics; bubble column; laser doppler anemometry LDA ; mass transfer; hydrodynamics; multiphase reactor; dispersion;

    Sammanfattning : Bubble columns are used in the chemical industry to perform gas liquid reactions, like oxidation, hydrogenation and fermentation. The objective of the present thesis was mainly to study the fluid dynamics of semi batch packed bubble columns at both atmospheric and pressurized conditions. LÄS MER
