Dynamic modeling and simulation of fixed bed adsorption process was carried out by explaining the behavior of breakthrough curve parameter. Adsorption of sulfur compound, present in road fuel, has posed a great challenge. A model of fixed bed adsorption of benzothiophene from fuel was formulated with non-ideal plug flow behavior and considered velocity variation along a column. The model was so...

The development and production of high performance equipment necessitate the use of passive cooling technology. In this paper, heat transfer study of convective-radiative straight fin with temperature-dependent thermal conductivity under the influence of magnetic field is carried out using Legendre wavelet collocation method. The numerical solution is used to investigate the effects of magnetic...

Aluminium zirconium tetrachlorohydrex glycine (AZG) is a popular antiperspirant/deodorant agent, formulated in various forms including the clear gels. Silicones are used for the preparation of these gels, giving them desirable characteristics. The aim of this study was to investigate the influence of various silicones, when used in combination, on the rheological properties of the resulting AZG...

Mesoporous nanostructured γ-Al2O3 powders were synthesized through multi- step precipitation procedures using the pH-swing technique. Structural and morphological characteristics in addition to the thermal behavior of the procured samples were characterized via X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fourier transform infrared (FT-IR) ...

The present work is an experimental account of the way in which several machine settings, particularly cylinder knock-over and dial-height, influence fabric dimensions, course length, bending behavior and load extension of fabrics produced on a circular knitting machine. The results show that there are certain optimum settings for such variables as knock-over depth and dial-height for producing...

In this study, a new approach for simulation of electric field enhancement ofplane wave laser around optical antenna was used to convert free-propagating opticalradiation to localized energy. A tapered gold tip design as a novel geometry of opticalantenna is introduced and numerically analyzed based on particle swarm optimization(PSO) by solving the Maxwell equations wit...

In this paper, influence of riveting process parameters, namely, riveting force, sheet thickness, friction coefficient and clearance fit are investigated on residual stress field and fatigue life of single riveted lap joint of AA2024 type. According to the effect of riveting induced residual stresses on fatigue life of riveted lap joint, these parameters are optimized to maximize the residual s...
