gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...

Blood flow in a narrow tube is described using the two-layered model in presence of an external uniform magnetic field. The model consists of a core region, enriched with various types of blood cells and a cell-free peripheral plasma layer. Also the constant heat flux convective heat transfer to fully developed blood flow is studied. The velocity and temperature profiles are determined. The exp...

A steady three-dimensional Magnetohydrodynamic (MHD) boundary layer viscous flow and heat transfer due to a permeable stretching sheet with prescribed surface heat flux is studied in presence of a uniform applied magnetic field transverse to the flow. Using the implicit finite-difference scheme, known as the Keller-box method, the nonlinear ordinary differential equations are solved. The veloci...

Ageneral solution,basedontheseparationofvariablesmethod,for the thermal spreadingresistance incompound annular sectors, is presented. Results are given for three heat  ux distributions: inverse parabolic, uniform, and parabolic proŽ les. The general solution can be used to model any number of equally spaced heat sources on a compound or isotropic annulus. Graphical results are presented for a ...

An analysis is performed to study the heat transfer characteristics of steady mixed convection flow over a permeable vertical flat plate embedded in an anisotropic fluid-saturated porous medium. The effects of uniform suction and injection on the flow field and heat transfer characteristics are numerically studied by employing an implicit finite difference Keller-box method. It is found that du...
