This paper is focused on the application of hybrid Single relaxation time lattice Boltzmann and finite volume methods in conjunction with discrete ordinates method to simulate coupled natural convection and volumetric radiation in differentially heated enclosure, filled with an absorbing, emitting and non-scattering gray medium. In this work, the velocity and temperature fields are calculated u...

The Dodewaard NPP was shut down in 1997 and is now in the decommissioning phase. All spent fuel has been removed from the plant and transferred to Sellafield, in the United Kingdom, for reprocessing. The last shipment of spent fuel from Dodewaard was made in April 2003. In May 2002 a license was granted to GKN, the operator of the NPP Dodewaard, to bring and keep the plant in a safe enclosure. ...

organization of living environment is possible through a clear definition of private and public arenas and determinationof a spatial hierarchy. such defined arenas increase the sense of belonging to the environment which personalizesresidential environments. enclosure is among the quantities that play a significant role in defining the spaces. in fact,enclosure is the factor that defines a spac...

The aim of this study is to apprehend the function of the stone enclosures during the Neolithic and the Bronze Age. Some enclosures well positioned in the Corsican chronology have been chosen to show an evolution of their dimensions, of dry-stone techniques used and of the function of the structures excavated within enclosures. The results prove that during the Neolithic, the whole habitat is i...

PCB structures like traces couple to the cavity field inside of an enclosure. It has been presented before that the coupling of a trace inside of a homogeneous cavity is caused just by its vertical segments on the trace ends. For an inhomogeneous cavity, consisting of a FR4 PCB layer and an air layer, we show that a trace couples along its whole length. The different coupling must be considered...

Behavioral studies in non-human primates have become ideal models for further investigations into advanced cognitive function in humans. To date, there is no systematic ethogram of the cynomolgus monkey (Macaca fascicularis) in a free enclosure. In a field observation of 6012 subjects, 107 distinct behaviors of M. fascicularis were preliminarily described. 83 of these behaviors were then indepe...

Strontium (atomic symbol Sr) is a silvery-white alkaline earth metal that exists in several stable (e.g., Sr-86 and Sr-88) and several radioactive (e.g., Sr-89 and Sr-90) isotopic states. Stable strontium and its salts have many industrial uses, such as providing the red color in pyrotechnic devices such as tracer bullets, distress signal rockets, flares, and fireworks. In medicine, strontium b...

Literature about entropy generation analysis of a wavy enclosure is scare. In this paper. a FORTRAN cod using an explicit finite-volume method was provided for estimating the entropy production due to the natural convection heat transfer in a cosine wavy absorber solar collector. The volumetric entropy generation terms both the heat transfer term and the friction term were straightly calculated...

Contemporary design of large telescopes requires optimization of the telescope environment in order to fully realize the capabilities of advanced mirror technology, telescope control and instrumentation. Telescope enclosure design is a critical element in providing this optimized environment. Enclosures must protect the telescope while minimizing the local degradation of image quality, and the ...
