Electricity system security in Jordan: A response for arab uprising.

Jordan energy sector is characterized by the high dependency on imported energy and high growth rate of energy demands. The location of Jordan in a conflict hot spot makes the energy security of high interest for the Jordanian policy maker. This article investigates the impact of regional conflicts on Jordanian energy sector and tracks the development of electricity system security before and after the first wave of Arab uprising and the turmoil associated with it.

Galerkin finite element analysis of magneto two-phase nanofluid flowing in double wavy enclosure comprehending an adiabatic rotating cylinder.

In this work, the finite element method is employed to simulate heat transfer and irreversibilities in a mixed convection two-phase flow through a wavy enclosure filled with water-alumina nanoliquid and contains a rotating solid cylinder in the presence of a uniform magnetic field. Impact of the variations of undulations number (0 ≤ N ≤ 5), Ra (10 ≤ Ra ≤ 10), Ha (0 ≤ Ha ≤ 100), and angular rotational velocity (- 500 ≤ Ω ≤ 500) were presented. Isotherms distribution, streamlines and isentropic lines are displayed.

Entropy Generation Optimization for Rarified Nanofluid Flows in a Square Cavity with Two Fins at the Hot Wall.

Computational Fluid Dynamics (CFD) is utilized to study entropy generation for the rarefied steady state laminar 2-D flow of air-AlO nanofluid in a square cavity equipped with two solid fins at the hot wall. Such flows are of great importance in industrial applications, such as the cooling of electronic equipment and nuclear reactors. In this current study, effects of the Knudsen number (), Rayleigh number () and the nano solid particle's volume fraction ( ϕ ) on entropy generation were investigated.
