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

    Author : Urban Wählby; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cooking; impingement; meat; mass transfer; buns; food quality; heat transfer;

    Abstract : 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. READ MORE

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

    Author : Fredrik Ekström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TWC; optimization; exhaust; laboratory reactors; catalytic converter; catalysis; pressure drop; entrance effects; CFD; mass transfer; pulsations; flow distribution;

    Abstract : 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. READ MORE

  5. 3. Mass transfer during isothermal drying of a porous solid containing multicomponent liquid mixtures

    Author : Rafael Gamero; KTH; []
    Keywords : internal mass transfer; capillary flow; multicomponent; diffusion; solvent mixtures;

    Abstract : Mass transfer in a porous solid, partially saturated with asingle solvent and multicomponent liquid mixtures, has beenexperimentally and theoretically studied. A porous materialcontaining single liquids and mixtures of organic solvents wasisothermally dried. READ MORE

  6. 4. On-Engine Turbocharger Performance Considering Heat Transfer

    Author : Habib Aghaali; Hans-Erik Ångström; Jose R. Serrrano; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

    Abstract : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. READ MORE

  7. 5. SOFC Modeling Considering Mass and Heat Transfer, Fluid Flow with Internal Reforming Reactions

    Author : Martin Andersson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; COMSOL Multiphysics; Modeling; Catalyst; CFD; Transport phenomena; Internal reforming reaction; IT-SOFC; LTNE;

    Abstract : Fuel cells are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no emissions of greenhouse gases. Fuel cells have during recent years various improvements, however the technology is still in the early phases of development. READ MORE
