Enhancing heat transfer through surface modification using carbon nanostructures

Energy and nanotechnology: A combination of two promising and important fields in modern science. Due to a combination of impressive mechanical, electrical, thermal and chemical properties, carbon nanostructures are in the limelight.

A growing part of the research on nanotechnology focuses on heat transfer applications, fuelled by growing demand for more energy efficient industrial processes and developments in microelectronics. This thesis investigates heat transfer surface modification using carbon nanostructures. The subject of choice is nickel wire.

The heat transfer potential of the wires - with and without carbon nanostructures - is measured in a custom hot wire setup. The performance of the modified wires is combined with high resolution scanning electron microscope images. Together, they reveal a remarkable diversity in both performance and nanostructures present.
