Performance of SOFC stacks under partial internal reforming of methane

Solid Oxide Fuel Cell systems (SOFC) are developed for their electrical efficiency and versatility. Versatility stems from their tolerance towards CO and CH4, which allows for the use of various reformed fuels. Efficiency results from the direct conversion ...

Tubulo - a train-like miniature inspection climbing robot for ferromagnetic tubes

Francesco Mondada, Hannes Bleuler, Gilles Caprari, Roland Moser, Frédéric Rochat, Patrick Schoeneich, Olivier Truong-Dat Nguyen

A train-like miniature climbing inspection robot for ferromagnetic tubes is presented in this paper. Using magnetic wheels, it climbs in tubes of 25 mm of diameter and bigger in any orientation, and pass bends with curvatures above 150 mm in some cases. It ...

Prediction Of Critical Heat Flux In Microchannels

John Richard Thome, Lorenzo Consolini

An overview of the state-of-the-art of predicting critical heat flux during saturated flow boiling in microchannels is presented. First, a selection of experimental results is described for single channels and for multi-channels in parallel, including non- ...

Experimental Evidence of Hydroacoustic Pressure Waves in a Francis Turbine Elbow Draft Tube for Low Discharge Conditions

François Avellan, Christophe Nicolet

The complex three-dimensional unsteady flow developing in the draft tube of a Francis turbine is responsible for pressure fluctuations, which could prevent the whole hydropower plant from operating safely. Indeed, the Francis draft tube is subjected to inl ...

A three dimensional probe positioner

Ivo Furno, Xin Sun

In order to sort out the physics that is important in many plasma experiments, data in three dimensions 3D are becoming necessary. Access to the usual cylindrical vacuum vessel is typically restricted to radially or axially insertable probes that can pivot ...

Subcooled and saturated water flow boiling pressure drop in small diameter helical coils at low pressure

Andrea Cioncolini

Experimental pressure drop results on boiling water flow through three helical coils of tube inner diameter of 4.03 mm and 4.98 mm and coil diameter to tube diameter ratio of 26.1, 64.1 and 93.3 are presented. Both subcooled and saturated flow boiling are ...

Heat Transfer in Confined Forced-Flow Boiling

John Richard Thome, Wei Zhang, Lorenzo Consolini

Remarkably different behaviors are found when comparing micro-scale flow boiling heat transfer data by distinct authors, even under similar experimental conditions. Such differences are almost certainly related to the complexity of confined forced-flow boi ...
