Mixed convection of Cu-Water nanofluid is studied numerically in a shallow inclined enclosure by applying lattice Boltzmann method. The D2Q9 lattice and internal energy distribution function based on the BGK collision operator are used in order to develop the thermal flow field. The enclosure's hot lid has the constant velocity of U0 while its cold lower wall has no motion. Moreover, sidewalls ...

The carrying out of human activities an industrial nature involves the use, handling or accidental presence substances a toxic such as carbon oxide. this gas in closed semi-closed spaces can seriously affect body and when concentrations are high it lead to death. Knowing how oxide affects disperses into air is very important for establishing preventive measures. Also, order establish escape rou...

We studied immune responses of the jird Meriones crassus to different flea species belonging to the same family. We used jirds maintained in an outdoor enclosure (enclosure; N=18) and parasitized by fleas Xenopsylla conformis mycerini and Xenopsylla ramesis, and also jirds born in the laboratory to previously parasitized mothers (laboratory animals; N=23). We asked (i) whether cross-immunity to...

Source identification in an enclosure is not an easy task due to complicated wave interference and wall reflections, in particular, at mid-high frequencies. In this study, a phased beam tracing method was applied to the reconstruction of source pressures inside an enclosure at medium frequencies. First, surfaces of an extended source are divided into reasonably small segments. From each source ...

The free convection heat transfer of Cu-water nanofluids in a parallelogrammic enclosure filled with porous media is numerically analyzed. The bottom and top of the enclosure are insulated while the sidewalls are subject to limited temperature difference. The Darcy flow and the Tiwari and Das' nanofluid models are considered. The governing dimensionless partial differential equations are numeri...

In this paper we give an enclosure for the solution of the biharmonic problem and also for its gradient and Laplacian in the L2-norm, respectively.

Abstract – This paper investigates overvoltages on the SF6 substation enclosure caused by the switching operation of the interrupter. The paper analyzes the amplitude and the overvoltage duration on the substation enclosure. Switching overvoltages take part in the everyday drive of HV substations and constitute an undesired phenomenon that may often, beside transient disturbances, lead to undes...

Swarms of police drones, fleets of overhead delivery bots, and flocks of private security drones are set to multiply the complex interfaces between state, capital, and sense. This paper explores the military and economic enclosure of the atmosphere by drones. For centuries, capitalist enclosure has privatized and secured common spaces: territorializing new power relations into the soil. Enclosu...
