In this study, the two-dimensional Magnetohydrodynamic (MHD) boundary layer of stagnation-point flow in a nanofluid in the presence of thermal radiation is investigated. Using a similarity transform, the NavierStokes equations are reduced to a set of nonlinear ordinary differential equations. The similarity equations are solved numerically for three types of nanoparticles, namely copper (Cu), a...

Unidirectional carbon fiber-reinforced polymer nanocomposites were developed by adding alumina (Al2O3) and silicon carbide (SiC) nanoparticles using ultrasonication magnetic stirring. The uniform nanoparticle dispersions examined with a field-emission scanning electron microscope. nano-phase matrix was then utilized to fabricate the hybrid hand lay-up compression molding. weight fractions selec...

Abstract In the present work, nano-Aluminum oxide (Al2O3), nano-Silicon Carbide (SiC), or a hybrid of them were infused into epoxy resin with an ultrasonic system various weight percentage ratios nanoparticles. Small punch testing (SPT) and indirect tension adopted to measure tensile properties nanocomposites. Pin-on-ring wear was also performed examine performance Al2O3 SiC The Finite Element ...

As a model for electroconductive nanomaterials processing, the article examines incompressible mixed convection nanofluid flow with convective heat transport from stretching sheet under impact of Joule heating and radiative flux. The transformed non-linear boundary value problem is solved robust Chebyshev collocation technique. Validation conducted earlier published results. Nanoparticle concen...

AgAl2O3 nanocomposite were synthesized by solution combustion Technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. Samples prepared with different amount of silver, were characterized by XRD, BET, SEM and optical Absorption measurements. XRD analysis was used to determine the change in phase and size of the synthesized n...

We have studied the effect of different supports (CeO2, ZrO2, SiC, SiO2 and Al2O3) on catalytic performance phase stability Co3O4 nanoparticles during preferential oxidation CO (CO-PrOx) under H2-rich gas environments temperatures. Our results show that Co3O4/ZrO2 has superior activity, but transforms to Co0 consequently forms CH4 at relatively low The least reduced methanation active catalyst ...
