Dynamics of the solar granulation [PDF]
Astronomy & Astrophysics, 2001 Temporal series of quiet region images near the center of the Sun are analysed. The images, monochromatic and in white light, have been acquired at the French-Italian solar telescope THEMIS (Tenerife, Canarie, Spain) by the Italian panoramic monochromator IPM.

Modelling of solar granulation [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe present the essential features of the ANTARES code. ANTARES has been developed to perform the simulation of astrophysical flows in one, two, or three dimensions. Using, in particular, the option of grid refinement, we present results for solar granulation achieved at very high spatial resolution.

The Evolution of an Average Solar Granule [PDF]
International Astronomical Union Colloquium, 1980 AbstractHigh-resolution photographic spectra of the center of the solar disk have been obtained with the Vacuum Tower Telescope at Sacramento Peak Observatory. Two weak iron lines and the neighboring continuum were recorded with 40 sec time resolutions and better than 1” spatial resolution over a period of 40 min.

Effect of operating conditions and physico–chemical properties on the wet granulation kinetics in high shear mixer [PDF]
, 2009 The wet granulation process is sensitive to changes in product properties and process variables. The optimal process and formulation are based on the knowledge of the granule growth mechanisms and of the effects of product properties and process ...

Spectral Deconvolution With Deep Learning: Removing the Effects of Spectral PSF Broadening
Frontiers in Astronomy and Space Sciences, 2020 We explore novel methods of recovering the original spectral line profiles from data obtained by instruments that sample those profiles with an extended or multipeaked spectral transmission profile.

The scale of solar granulation
The Astrophysical Journal, 1978 We derive the observed scale of granulation as a consequence of a physical model. At scales smaller than granulation, horizontal radiative transport reduces temperature fluctuations and the resultant buoyancy forces in the surface layers. At scales only slightly larger than granulation, the dynamical pressure required to drive horizontal motions ...

Observations of a bright plume in solar granulation
, 2007 Aims.The aim of this paper is to analyze the thermal properties, oscillatory, and flow motions of a bright, long-lasting feature observed in solar granulation, which we call the plume.

STEAM GRANULATION VERSUS WET GRANULATION: IMPACT ON GRANULE AND TABLETS PROPERTIES
, 2023 Steam granulation (SG) involves the use of steam as the granulating medium instead of traditional liquid water [1]. Steam provides a higher diffusion rate into the powder bed and a more favourable thermal balance during the drying step.
