This work deals with under-ventilated pool fires in confined and mechanically ventilated enclosures. The objective is to demonstrate the suitability of reduced-scale experiments investigate combustion regimes case a enclosure, by analysing at two different scales. fire scenario consists dodecane liquid located room. Reduced-scale concern 0.031 m2 size inside 1.875 m3 enclosure large-scale 0.4 1...

the fluid flow and heat transfer in lid-driven enclosures filled with cu-water nanofluid is numerically investigated. the moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity field and pressure in the momentum...

it has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...

We study the enclosure method for the p-Calderón problem, which is a nonlinear generalization of the inverse conductivity problem due to Calderón that involves the p-Laplace equation. The method allows one to reconstruct the convex hull of an inclusion in the nonlinear model by using exponentially growing solutions introduced by Wolff. We justify this method for the penetrable obstacle case, wh...

Target enclosure by autonomous robots is useful formany practical applications, for example, surveillance of disaster sites. Scalability is important for autonomous robots because a larger group is more robust against breakdown, accidents, and failure. However, since the traditional models have discussed only the cases in which minimum number of robots enclose a single target, there has been no...

Recently, an alternative interval approximation F X ( ) for enclosing a factorable function f(x) in a given box X has been suggested. The enclosure is in the form of an affine interval function F X a X B i i i n ( ) = + ∑ =1 where only the additive term B is an interval, the coefficients ai being real numbers. The approximation is applicable to continuously differentiable, continuous and even d...

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...
