The shell and tube heat exchangers are devices used very much in the industrial processes in many applications. These elements can have characteristics very special, in its use as well as in its design, therefore each system being a particular problem. The program developed uses simultaneously the LMTD and the effectiveness-NTU methods to such important… (More)

We investigate theoretically the unsteady magnetohydrodynamic natural convection heat and mass transfer of a viscous, incompressible, electrically-conducting and radiating fluid over a porous vertical infinite plate. A uniform magnetic field of magnitude 0 B is applied normal to the SAHIN AHMED et al. 14 plate. An algebraic flux model is employed valid in… (More)

Considering the traditional design of residential electricity distribution networks in Australia and the possibility of reverse power flow due to increased solar photovoltaic (PV) power injection, the possibility of voltage rise is expected to increase. The paper reports voltage performance of low- (LV) and medium (MV) voltage networks under high… (More)

In this article, we have investigated quarkonium spectrum using the generalized Klein-Gordon equation. This has been done using suitable potentials and applying them in the Klein-Gordon equation mass term analytically and numerically. The simplicity of this model and the high accuracy of the achieved results, compared to other methods, for a relativistic… (More)

Nowadays, it is a common concern for modern electrical networks and energy management systems to derive an optimal operation management considering energy costs, pollutant emissions, and security, of the system in the presence of plug-in electric vehicles (PEVs). In this paper, a multiobjective optimization problem is solved to schedule power sources in a… (More)

Thermally activated flux motion and specific electric resistance in Y358 were studied under different magnetic fields ranging from 0 to 15 kOe. Through investigating the broadening of normal-superconducting transition, we found that the thermally-activated-flux-motion model can describe the electronic effect near the superconducting transition temperature.… (More)

Rotating disk flows arise in many areas of the electrochemical, biophysics, renewable energy systems and materials processing industries. Motivated by industrial applications, we examine a complex multi-physical coupled nonlinear heat transfer regime in the vicinity of a rotating disk incorporating thermal radiation, magnetohydrodynamics, and wall slip and… (More)

In this article, a method is presented for transforming the singular Lippmann-Schwinger integral equation to a matrix algebraic equation. This method of computing the matrix elements of the reaction and transition operators is used on the real axis and on the complex plane, respectively. By specifying the elements value of the reaction and transition matrix… (More)
