Electroplating of Horizontal Steel Cylinders in Unstirred Copper Sulphate Solutions

Magnetohydrodynamic Flow in Horizontal Concentric Cylinders

This article presents the exact solutions of the velocity and temperature fields for a steady fully developed magnetohydrodynamic flow of a viscous incompressible and electrically conducting fluid between two horizontal concentric cylinders. Our study focuses on the influence of the Hartmann number, Brinkman number, Péclet number and inner radius on the fluid temperature field, entropy generati...

Natural convection between two horizontal coaxial cylinders

The objective of our paper is to start the theoretical investigation of the most commonly used mathematical model for natural convection in a horizontal annulus. First, one shows existence of solutions for the unsteady problem. Then, for any Prandtl number and inverse relative gap width, existence and stability of a steady solution is proved, provided that the Rayleigh number is sufficiently sm...

Biosortion of Copper from Electroplating Effuluent and It’s Equilibrium Studies

The present work is concerned to remove Cu using the biosorption potential of fungal biomass Aspergillus oryzae. The dry fungal biomass was used to optimize various parameters such as contact time, initial metal ion concentration, pH, biomass loading etc. A maximum of 91% Copper removal was observed in 5 mg/L initial Copper metal ion concentration using dry Aspergillus oryzae biomass. The perce...

Residual Stresses in Rotating Steel Cylinders with Composite Surface Layers

After undergoing a manufacturing process, materials may exhibit internal stresses referred to as residual stresses. In steel-composite hybrid structures, residual stresses are typically formed due to the unequal thermal behaviour of the steel and composite. Thus, knowledge of the residual stress state is important in the assessment of the external-internal loading in steel-composite hybrid stru...
