The application of semi-solid metal forming technology to the production high-quality copper alloy parts has attracted more and attention. Accordingly, as key foundation technology, it is particularly important stably efficiently prepare slurry with high quality. purpose this study was innovatively optimize process parameters by combining multiple optimization algorithms stabilize preparation C...

This computational work explores the heat and mass transfer of copper water nanofluid flowing along an inclined plate with varying surface temperature concentration in presence a magnetic field radiation through permeable medium. The dimensionless governing equations are solved numerically using efficient finite-difference technique, which is fast convergent unconditionally stable. findings rev...

Two main types of subduction zones can be distinguished: (1) those where the subduction hinge migrates away from the upper plate; and (2) those in which the subduction hinge migrates toward the upper plate. Apart from a few exceptions, this distinction seems to apply particularly for W-directed subduction zones and Eor NE-directed subduction zones, respectively. Moreover, the rate of subduction...

An analysis of entropy generation in an MHD boundary layer flow of a viscous incompressible electrically conducting fluid past an inclined flat plate embedded in a porous media in a rotating system with Hall currents has been presented. The governing equations describing the flow have been solved analytically. The velocity field, induced magnetic field, shear stress and bulk temperature in the ...

We investigate the stability of a granular monolayer composed of spherical grains on an inclined plate. When the tilt angle alpha increases, some reorganizations are observed throughout the pile. The packing fraction rho of the packing evolves by successive jumps. Those discontinuous events precede the collapse of the pile at a critical angle alphac. The occurrence of precursors before avalanch...

The effect of heat transfer on unsteady MHD couette flow between two infinite parallel porous plates in an inclined magnetic field has been investigated. The lower plate is considered porous. The governing equations of the flow field are solved by variable perturbation technique and the expression for the velocity and temperature are obtained. The effects of various parameters such as Hartman n...
