Non-linear modelling of saturated internal and external MHD instabilities in tokamaks

Macroscopic instabilities and their unfavourable effects on plasma confinement pose a central challenge for the development of reactor relevant tokamak scenarios. Some promising operation scenarios feature extended regions of low magnetic shear. These are ...

Void fraction prediction in annular two-phase flow

John Richard Thome, Andrea Cioncolini

A new method to predict the void fraction in annular two-phase flow in macroscale and microscale channels is presented. The underlying experimental database contains 2673 data points collected from 29 different literature studies for 8 different gas-liquid ...

Introduction aux nouveaux bilans énergétiques

Lucien Borel

Exergy analysis of systems is extremely rich as it uses the so-called exergy accountancy which takes into account first and second principles of thermodynamics. This exergetic accountancy enables to quantitatively evaluate what is calles qualitatively the ...

Performances et limites de chaudières à gaz de centrales solaires

Production of electricity from solar energy is mainly achieved by means of solar cells or by central receiver power plants. These plants are driven by vapor turbines where the fluid temperature is about l000°F or by gas turbines in which gas temperature ex ...

Non-equilibrium effects during the sudden vaporization of saturated water / Vaporization of superheated water under sudden depressurization

Daniel Favrat

The vaporization of an entrapped mass of saturated water suddenly allowed to expand is studied both experimentally and theoretically. In the experimental set-up, the water is initially pressurized by a piston at the closed end of a cylinder and heated to t ...
