Numeric and experimental survey of a condenser to porous media of granite

This article evaluates the numeric and experimental survey of a distiller's condenser for brackish water whose saltiness varies between 5 to 10 g/L. The condenser is a cylindrical tank, in which is vertically arranged and the pieces of granite constituent of porous media. The governing equations that describe the transfers are deduced from a thermal and mass global balance within the condenser. Finite difference...

Alternating current (AC) electroosmotic flow of generalized Maxwell fluids through a circular microtube

An analytical solution for the time periodic electroosmotic flow (EOF) of the generalized Maxwell model through a circular microtube is presented by solving the linearized Poisson-Boltzmann equation, together with Cauchy momentum equation and General Maxwell constitutive equation. By numerical calculations, we find that for lower Ω and smaller De, classical plug-like profile of Newtonian fluids is reduced. At...

Transient magnetohydrodynamic (MHD) flow of a visco-elastic fluid past an infinite vertical porous plate embedded in a porous medium with Hall current and slip condition in a rotating system

An attempt is made to present a theoretical analysis of a transient magnetohydrodynamic (MHD) flow of a visco-elastic fluid (Walter’s B’) past an infinite vertical porous plate embedded in a porous medium with constant permeability in a rotating system in the presence of Hall current when the plate temperature varies periodically with time. The expressions for the non-dimensional velocity field, temperature...

The Dirac equation with position-dependent mass for the modified Pöschl-Teller potential and its solution

The Dirac-modified Pöschl-Teller problem with position dependent mass is investigated within the framework of the asymptotic iteration method in N dimensions. Any -state solutions are obtained by using the exponential approximation for the centrifugal term. The energy eigenvalues and two-component spinor corresponding eigenfunctions are determined for different  screening...

Modeling and simulation of UPFC using PSCAD/EMTDC

This paper proposes to model and simulate a unified power flow controller (UPFC) in power system computer aided design and electromagnetic transient direct current (PSCAD/EMTDC) environment. The series converter of the UPFC controls the transmission line real/reactive power flow and the shunt converter of the UPFC controls the UPFC bus voltage/shunt reactive power and the DC link capacitor voltage. The real power demand...

Teachers’ views about the application of secondary Physics course curriculum

The main purpose of this study is to investigate teachers’ views about the application of secondary Physics curriculum (9, 10, and 11 grade) whose application had been started from 2008 to 2009 academic years and gradually extended to other grades. The study is a descriptive survey for determining the situation. In the study, a scanning model has been used. Sample of the study consists of 82 Physics teachers who...

Exact and explicit solutions for the discrete Burgers equation by means of the Exp-function method

In recent years, various direct methods were proposed to find exact solutions not only for nonlinear partial differential equations but also for nonlinear differential-difference equations (NDDEs). In this paper, the Exp-function method was extended to the discrete Burgers equation for searching traveling waves in closed forms. It was shown that the equation supported discrete solitary wave solutions. Our results,...

The effect of mineral admixtures and micronized calcite on alkali silica reaction expansions in the usage of aggregates from different origin

This paper investigates the effectiveness of two zeolites with different reactive silica content, fly ash (FA), blast furnace slag (BFC), silica fume (SF), and micronized calcite (MC) in reducing expansion of concrete due to alkali-silica reaction. Also in this research, effects of three different cement usages were investigated by using accelerated mortar bar method, ASTM C1260. Five different aggregates, three natural...

Coastal geoid improvement using airborne gravimetric data in the United Arab Emirates

Military survey department (MSD) of The United Arab Emirates (UAE) has undertaken the Airborne Gravity Survey Project for the marine area of the country. The main purpose for the implementation of the airborne gravity survey for the marine area is to improve the existing gravimetric geoid of the UAE. The airborne gravity data was estimated to have accuracy better than 2.0 mGal. The first gravimetric geoid for the...
