  2. 6. Engineering nanomaterials with enhanced functionality

    Author : Shanghua Li; Mamoun Muhammed; Saad Elraghy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PMMA-ZnO; nanocomposite; hybrid material; in situ sol-gel polymerization; quantum dots; UV-shielding; Nanostructured surface; Pool boiling; Heat transfer coefficient; Bubble nucleation; Enhanced boiling; dendritic branch; Electrodeposition; Nanoengineering; Materials chemistry; Materialkemi;

    Abstract : This thesis deals with the engineering of novel nanomaterials, particularly nanocomposites and nanostructured surfaces with enhanced functionalities. The study includes two parts; in the first part, an in situ sol-gel polymerization approach is used for the synthesis of polymer-inorganic hybrid material and its exceptional transparent UV-shielding effect has been investigated.

  4. 7. Phase Change Phenomena During Fluid Flow in Microchannels

    Author : Rashid Ali; Björn E Palm; Gian Piero Celata; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microchannels; Boiling; Heat Transfer; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

    Abstract : Phase change phenomena of a fluid flowing in a micro channel may be exploited to make the heat exchangers more compact and energy efficient. Compact heat exchangers offer several advantages such as light weight, low cost, energy efficiency, capability of removing high heat fluxes and charge reduction are a few to mention. READ MORE

  6. 9. Numerical Modelling of Subcooled Nucleate Boiling for Thermal Management Solutions Using OpenFOAM

    Author : Achref Rabhi; Rebei Bel Fdhila; Konstantinos Kyprianidis; Ioanna Aslanidou; Christophe Duwig; Mälardalens universitet; []
    Keywords : Computational Fluid Dynamics; Boiling Flows; Two-phase cooling; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Two-phase cooling solutions employing subcooled nucleate boiling flows e.g. thermosyphons, have gained a special interest during the last few decades. This interest stems from their enhanced ability to remove extremely high heat fluxes, while keeping a uniform surface temperature. READ MORE
