Free convection is widely used in engineering applications, including solar energy, electronic devices, nuclear and heat exchangers. A computational simulation utilizing Ansys Fluent-CFD was employed to examine the natural transfer inside a square cavity filled with pure water saturated metal foam as porous medium (porosity ɛ =0.9). The enclosure's lower wavy wall exhibits high temperature (Th)...

In this article, we present two different approaches for obtaining quantitative inequalities in the context of parabolic optimal control problems. Our model consists a linearly controlled heat equation with Dirichlet boundary condition (uf)t−Δuf=f, f being control. We seek to maximise functional JT(f)≔12∬(0;T)×Ωuf2 or, some ɛ>0, JTɛ(f)≔12∬(0;T)×Ωuf2+ɛ∫Ωuf2(T,⋅) and obtain estimates these maximi...

The notion of a tensor product of topological groups and modules is important in theory of topological groups, algebraic number theory. The tensor product of compact zero-dimensional modules over a pseudocompact algebra was introduced in [B] and for the commutative case in [GD], [L]. The notion of a tensor product of abelian groups was introduced in [H]. The tensor product of modules over commu...

The Late Cretaceous is marked by geodynamical changes including Africa-Eurasia convergence that resulted in the narrowing of Tethys Ocean and ophiolite obduction along southern margin various continental blocks eastern Tethys. Geochemical mineralogical analyses were performed on Shahneshin section (Zagros Basin - Tethys), to explore consequences this evolution oceanic circulation, estimate role...

in this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. the polymers were characterized by nuclear magnetic resonance (nmr) spectrometry, fourier transform infrared spectroscopy (f...
