Flow boiling in horizontal flattened tubes: Part I – Two-phase frictional pressure drop results and model

John Richard Thome, Jesus Moreno Quiben, Ricardo Lima

Experiments of diabatic two-phase pressure drops in flow boiling were conducted in four horizontal flattened smooth copper tubes with two different heights of 2 and 3 mm. The equivalent diameters of the flat tubes are 8.6, 7.17. 6.25, and 5.3 mm. The worki ...

Ammonia two-phase flow in a horizontal smooth tube: Flow pattern observations, diabatic and adiabatic frictional pressure drops and assessment of prediction methods

John Richard Thome, Jesus Moreno Quiben, Ricardo Lima

The present study illustrates new experimental two-phase flow pattern observations together with diabatic boiling and adiabatic two-phase frictional pressure drop results for ammonia (R7117) flowing inside a 14-mm internal diameter, smooth horizontal stain ...

Experimental investigation of a direct driven radial compressor for domestic heat pumps

Daniel Favrat, Jürg Alexander Schiffmann

The presence of oil in domestic heat pumps is an obstacle toward higher efﬁciency, particularly for enhanced surface evaporators and for advanced concepts based on two- stage cycles. Very compact direct driven radial compressors supported on oil-free beari ...

Application of single pan thermal analysis to Cu-Sn peritectic alloys

Michel Rappaz, Thomas Campanella

Single pan thermal analyses (SPTA) have been performed on Cu-14.5 wt.% Sn, Cu-21.3 wt.% Sri and Cu-26.8 wt.% Sit peritectic alloys. For this purpose, a SPTA assembly has been built and calibrated. As the latent heat is a function of temperature and composi ...

Cross-field transport by instabilities and blobs in a magnetized toroidal plasma

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Mario Ludovico Podesta, Francesca Maria Poli

The mechanisms for anomalous transport across the magnetic field are investigated in a toroidal magnetized plasma. The role of plasma instabilities and macroscopic density structures (blobs) is discussed. Examples from a scenario with open magnetic field l ...

Energy integration study of a multi-effect evaporator

François Maréchal, Zoé Périn-Levasseur, Vanessa Palese

In the pulp and paper industry, multi-effect evaporators are used to evaporate water from black liquor solutions to allow its recycle as chemicals and fuel for the process. The thermodynamic principle of the multi-effect evaporator consists in a serie of r ...

A magnetic heat pump with porous magneto caloric material

Didier Albert Simon Vuarnoz, Marc Diebold

At present magnetic refrigeration shows a realistic potential to penetrate into some niche markets in the field of cold and hot "production". It is well known that a refrigerator for cooling and a heat pump for heating are machines based on the same princi ...
