Kinetic modeling of solid-gas reactions at reactor scale: A general approach [PDF]

, 2013
International audienceA rigorous simulation of industrial reactors in the case of solid-gas reacting systems is a complicated task due to several difficulties linked to the kinetic problem at the scale of the solid grains and to the problem of gas and ...

Pressure drop across micro-pin heat sinks under boiling conditions [PDF]

, 2009
Two-phase pressure drop was studied in four different micro pin fin heat sinks. Micro pin fin heat sinks used in the current studies were operated under boiling conditions using water and R-123 as working fluids.

Heat transfer and flow characteristics in horizontal spiral coils with flat tubes and rectangular ribs: CFD and optimization

International Journal of Thermofluids
The present work focuses on the analysis of heat transfer and flow characteristics in a horizontal spiral coil with rectangular ribbed flat tubes. The influence of Reynolds numbers (Re) ranging from 3000 to 12,000, relative rib height (Hn) from 0.04 to 0.

Kinetic modeling of solid-gas reactions at reactor scale: A general approach [PDF]

, 2011
International audienceUnderstanding the industrial reactors behavior is a difficult task in the case of solid state reactions such as solid-gas reactions. Indeed the solid phase is a granular medium through which circulate gaseous reactants and products.

An extensive photometric study of the Blazhko RR Lyrae star MW Lyr: II. Changes in the physical parameters

, 2009
The analysis of the multicolour photometric observations of MW Lyr, a large modulation amplitude Blazhko variable, shows for the first time how the mean global physical parameters vary during the Blazhko cycle.

The Konkoly Blazhko Survey: Is light-curve modulation a common property of RRab stars?

, 2009
A systematic survey to establish the true incidence rate of the Blazhko modulation among short-period, fundamental-mode, Galactic field RR Lyrae stars has been accomplished. The Konkoly Blazhko Survey (KBS) was initiated in 2004. Since then more than 750
