We propose in this paper, a numerical study of a planar impacting jet flow. The flow is assumed isothermal, laminar and unconfined. The developed computer code is based on the finite volume method, which was used to discretize the N-S equations. The…

The present paper aims at providing a theoretical overview of English for Specific Purposes as one of the major areas of EFL teaching since its beginnings in the 1960s. It presents the developments related with the theoretical aspects concerning ESP…

First principles calculations of the second and third order elastic constants of the cubic silicon carbide β-SiC have been accomplished using the density functional theory within the local density approximationand the pseudopotential plane-wave…

In this work, we investigate the influence of temperature on the series and shunt resistances of polycrystalline silicon solar cells and then to determine the specific expressions of both parasitic resistances as function of temperature. We have…

In this paper, we develop a mathematical model, which calculate the temperature and thermal contact resistance distributions in a multilayer media. This work is composed of two parts. The first part concerns the analytical solution of the conduction…
