  1. 1. Investigation of heat transfer and mass transfer parameters in a convection oven for model foods

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Chandana Mysore Somashekar; [2020]
    Keywords : Food engineering; Livsmedelsteknik; Technology and Engineering;

    Abstract : Forced air convection systems are the most preferred design of choice in many of the industrial-scale convection ovens. In this study, experimental investigation on convective heat transfer and mass transfer within a forced air convection oven was performed at different oven temperatures (100℃, 110℃ and 120℃) and at flow velocity (2 m/s, 3 m/s and 4 m/s) using potato slices (10*10*60 mm) as model food.

  4. 3. Heat exchange phenomena and COP evaluation in heat pump systems coupled to single borehole heat exchangers

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Francesco Casellato; [2013]
    Keywords : borehole; COP; convection; geothermal; heat pump;

    Abstract : In recent years a growing interest in Borehole Heat Exchangers (BHEs) has been shown in Europe thanks to the increase of installations in systems connected to Ground Source Heat Pumps (GSHPs) used for heating and cooling needs. Different geometries and technical solutions have been de- veloped in order to improve heat exchange with the ground, accompanied by several descriptive models. READ MORE

  5. 4. Modeling of electric arc furnaces (EAF) with electromagnetic stirring

    University essay from KTH/Materialvetenskap

    Author : Niloofar Arzpeyma; [2011]
    Keywords : electric arc furnace; electromagnetic stirring; natural convection;

    Abstract : The influence of electromagnetic stirring in an electric arc furnace (EAF) has been studied. Using numerical modeling the effect of electromagnetic stirring on the thermal stratification and fluid flow has been investigated. READ MORE

  6. 5. Nocturnal cooling : Study of heat transfer from a flat-plate solar collector

    University essay from Fakulteten för teknik- och naturvetenskap

    Author : Helena Johansson; [2008]
    Keywords : flat-plate solar collector; nocturnal radiation; convection; COMSOL Multiphysics; simulation; modelling; heat transfer; effectiveness-NTU method; heat pump; Thermia;

    Abstract : This thesis investigates the possibility of using an unglazed flat-plate solar collector as a cooling radiator. The solar collector will be connected to the condenser of a heat pump and used as cooler during nighttime. Daytime the solar collector will be connected to the evaporator of the heat pump and used as heat source. READ MORE
