1. Engineering nanomaterials with enhanced functionality
Sammanfattning : 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.

3. Enhanced Boiling Heat Transfer on a Dendritic and Micro-Porous Copper Structure
Sammanfattning : A novel surface structure comprising dendritically ordered nano-particles of copper was developed during the duration of this thesis research project. A high current density electrodeposition process, where hydrogen bubbles functioned as a dynamic mask for the materials deposition, was used as a basic fabrication method. LÄS MER
4. Numerical Modelling of Subcooled Nucleate Boiling for Thermal Management Solutions Using OpenFOAM
Sammanfattning : 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. LÄS MER
5. Flow Boiling Heat Transfer and Pressure Drop. Experiments and Model Development for Complex Geometries
Sammanfattning : Two very different evaporator geometries, a dimple plate and a herringbone microfin tube, have been studied. Heat transfer and pressure drop for both pure refrigerants and refrigerant mixtures have been determined experimentally. LÄS MER
