  1. 1. Pool Boiling on Structured Surfaces: Heat Transfer and Critical Heat Flux : -Experiments and Mechanistic Modelling

    University dissertation from Department of Energy Sciences, Lund University

    Author : Zhen Cao; [2019-09-30]
    Keywords : pool boiling; heat transfer; critical heat flux; bubble dynamics; surface modification;

    Abstract : In this thesis, pool boiling heat transfer was experimentally studied on structured surfaces with dielectric liquids (HFE-7200, NOVEC-649, FC-72), organic liquids (Acetone, Pentane) and deionized water.In the first step, nanoparticle coatings on copper surfaces were prepared by an electrophoretic deposition method, with Cu-Zn nanoparticles (100 nm) and Cu nanoparticles (150 nm).

  2. 2. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

    University dissertation from Stockholm : Materialvetenskap

    Author : Akira Yamauchi; [2001]
    Keywords : Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

    Abstract : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. READ MORE

  3. 3. The ORC method

    University dissertation from Institutionen för byggnader och installationer

    Author : Jan Akander; [2000]
    Keywords : ;

    Abstract : The ORC Method (Optimised RC-networks) provides a means ofmodelling one- or multidimensional heat transfer in buildingcomponents, in this context within building simulationenvironments. The methodology is shown, primarily applied toheat transfer in multilayer building components. READ MORE

  4. 4. Determination of the Thermal Conductivity of the Insulation in District Heating Mains. Field measurements

    University dissertation from Institutionen för byggnader och installationer

    Author : Margaretha Borgström; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measuring method; heat flux sensor; heat flow measurement; thermal conductivity; district heating main; field measurements;

    Abstract : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains. The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.
