Influence of sample processing parameters on thermal boundary conductance value in an Al/AlN system

Christian Monachon, Ludger Weber, Mohamad Hojeij

The influence of sample processing parameters on the thermal boundary conductance (TBC) between aluminum and aluminum nitride has been investigated by transient thermoreflectance. An evaporated Al layer on the polished substrate yielded a TBC at ambient of ...

Boiling on a Tube Bundle

Eugene van Rooyen

The complexity of two-phase flow boiling on a tube bundle presents many challenges to the understanding of the physical phenomena taking place. It is important to quantify these numerous heat flow mechanisms in order to better describe the performance of t ...

Polarization attributes of stimulated Brillouin scattering slow light in fiber

Luc Thévenaz

The polarization-related properties of stimulated Brillouin scattering (SBS) processes in long, randomly birefringent, standard optical fibers are examined. Evolution equations for the pump and signal waves, in the presence of both birefringence and SBS, a ...

Green Cooling of High Performance Micro Processors: Parametric Study between Flow Boiling and Water Cooling

John Richard Thome, Jackson Braz Marcinichen, Jonathan Olivier

Due to the increase in energy prices and spiralling consumption, there is a need to greatly reduce the cost of electricity within data centers, where it makes up 50% of the total cost of the IT infrastructure. A technological solution to this is using on-c ...

A Review of On-Chip Micro-Evaporation: Experimental Evaluation of Liquid Pumping and Vapor Compression Driven Cooling Systems and Control

John Richard Thome, Jackson Braz Marcinichen, Jonathan Olivier

Thermal designers of data centers and server manufacturers are showing a greater concern regarding the cooling of the new generation data centers, which consume considerably more electricity and dissipate much more waste heat, a situation that is creating ...

Falling-Film Evaporation On Tube Bundle With Plain And Enhanced Tubes-Part I: Experimental Results

John Richard Thome, Mathieu Habert

The complexities of two-phase flow and falling-film evaporation on a tube bundle present important challenges in the design of heat exchangers and the understanding of the physical phenomena taking place. The development of structured surfaces to enhance n ...

Falling-Film Evaporation On Tube Bundle With Plain And Enhanced Tubes-Part Ii: New Prediction Methods

John Richard Thome, Mathieu Habert

Many parameters influence the falling-film evaporation process and, despite numerous studies, the basic mechanisms remain only partially clear, making the prediction of heat transfer still mainly an empirical process. The most important thermal design para ...

Stenciled conducting bismuth nanowires

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Oscar Vazquez Mena, Katrin Sidler Arnet, Sam Neuser

Stencil lithography is used here for the fabrication of bismuth nanowires using thermal evaporation. This technique provides good electrical contact resistance by having the nanowire structure and the contact pads deposited at the same time. It has also th ...

Heat Transfer and Visualization of Falling Film Evaporation on a Tube Bundle

Marcel Christians

Horizontal falling film evaporators have the potential of displacing flooded evaporators in industry, due to advantages such as lower required refrigerant charge and lower pressure drop. However, there is a need to improve the understanding of falling film ...
