Study of the inter-particle necks in selective laser sintering

Rémy Glardon, Jamasp Jhabvala, Eric Boillat

Purpose – Since pulsed lasers are mainly used in selective laser sintering (SLS) – contrarily to selective laser melting (SLM) – only the exterior of the powder particles is molten while their core stays solid. The purpose of this paper is to investigate t ...

Experimental and Numerical Investigation of a Fully Confined Impingement Round Jet

Peter Ott, Alexandros Terzis, Gwenael Hannema, Gabriel Charles Gnaegi, Oriana Caggese

The heat transfer characteristics of a fully confined impingement jet are experimentally and numerically evaluated. Full surface heat transfer coefficient distributions are obtained for the target and impingement plate of the model using the transient liqu ...

Two-phase heat transfer and high-speed visualization of refrigerant flows in 100 × 100 μm2 silicon multi-microchannels

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

Two-phase flow boiling of R245fa, R236fa, and R1234ze(E) in 100 × 100 μm2 parallel microchannels for cooling of future 3D-ICs has been investigated. Significant flow instabilities, back flow, and non-uniform flow distribution among the channels were observ ...

Experimental and numerical investigation of narrow impingement cooling channels

Peter Ott, Alexandros Terzis, Bernhard Weigand

Impingement cooling effectiveness of gas turbine vanes and blades can be further increased due to the manufacturing feasibility of integrally cast airfoils which can provide narrow impingement cooling cavities. This study examines experimentally using the ...

Reinforcement of CVD grown multi-walled carbon nanotubes by high temperature annealing

László Forró, Arnaud Magrez, Rita Smajda, Massimo Spina

We report on the increase of the Young's modulus (E) of chemical vapor deposition (CVD) grown multi-walled carbon nanotubes (MWNTs) upon high temperature heat treatment. The post heat-treatment at 2200-2800 degrees C in a controlled atmosphere results in a ...

Numerical investigation of hydrodynamics and heat transfer of elongated bubbles during flow boiling in a microchannel

John Richard Thome, Mirco Magnini

Flow boiling within microchannels has been explored intensively in the last decade due to their capability to remove high heat fluxes from microelectronic devices. However, the contribution of experiments to the understanding of the local features of the f ...

Heat pump integration in a cheese factory

François Maréchal, Helen Carla Becker

The aim of process integration is to increase the efficiency and to reduce the energy consumption, operating costs and CO 2 emissions of an industrial process. The proposed methodology is applied to a real case study of a cheese factory with non-simultaneo ...

Modified Wilson Plots for Enhanced Heat Transfer Experiments: Current Status and Future Perspectives

John Richard Thome, Marcel Christians, Eugene van Rooyen

Heat transfer coefficients for enhanced tubes are typically measured indirectly using the "Wilson plot" method to first characterize the thermal performance of the one side (heating or cooling supply) and then to obtain the heat transfer data for the enhan ...
