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

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 ...

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 ...

Heat transfer assembly

John Richard Thome

A heat transfer assembly for transferring heat from a heat generating device (5) to a circulating fluid, said heat transfer assembly comprising - an evaporator device (3) having at least one microchannel (1) formed therein, in thermally conductive contact ...

DC performance of subsize NbTi cable-in-conduit conductors

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

Five subsize NbTi cable-in-conduit conductors with parametric variations were fabricated and their DC performance was tested in the SULTAN facility. A comparison of the measured strand data and the cable performances clearly indicates that the current carr ...

Particle transport with high power central ECH and ECCD in TCV

Ivo Furno, Henri Weisen

A coupled heat and particle transport phenomenon, leading to particle depletion from the plasma core is observed in a variety of plasma conditions with centrally deposited electron cyclotron heating and electron cyclotron current drive in TCV. This phenome ...

Cage exit probability versus excess energy in the photodissociation of matrix-isolated HCl

Majed Chergui

Dissocn. efficiencies for excitation of the repulsive A 1P state of HCl were recorded in Xe, Kr, and Ar matrixes for photon energies between 5 and 10 eV from the content of dissocn. products and quantum efficiencies were derived with the absorption spectra ...

Anharmonicity And High-Temperature Heat-Capacity Of Crystals - The Examples Of Ca2GeO4, Mg2GeO4 And CaMgGeO4 Olivines

Philippe Gillet

Drop-calorimetry determinations of the isobaric heat capacity (C(P)) of Mg2GeO4, Ca2GeO4 and CaMgGeO4 have been made up to 1700 K. The thermal expansion coefficient (alpha) of these olivine germanates has been determined from high-temperature X-ray measure ...

The heat generated by yeast cultures with a mixed metabolism in the transition between respiration and fermentation

Urs von Stockar

The heat generated by both batch and continuous cultures of the yeast Kluyveromycs fragilis was studied using a modified bench scale calorimeter. Batch cultures were used to measure the heat dissipation rates and the heat yields during fully aerobic and co ...

Calorimetric investigation of aerobic fermentations

Urs von Stockar, Ian William Marison

A modified bench scale calorimeter has been employed to det. the heat generated by various microbial strains growing on a range of different substrates, covering degrees of redn. from 3 to 6.13. The results are analyzed and interpreted in the light of coup ...
