“…The magnetohydrodynamic (MHD) boundary layer ow of a viscous incompressible uid which is electrically conducted has huge applications in industry and technological sectors, like cooling of nuclear reactors, the extrusion of plastics, textile industry, puri cation of crude oil, polymer technology, geothermal energy extractions, metallurgy, drug delivery and biological transportation [21,22]. The application of the magnetic eld produces a Lorentz force that increase the mixing processes as an active micro mixing mechanism.…”

An unsteady, laminar, mixed convective stagnation point nano uid ow through a permeable stretching at surface using internal heat source or sink and partial slip is investigated. The e ects of thermophoresis and Brownian motion parameters are revised on the traditional model of nano uid for which nano uid particle volume fraction is passively controlled on the boundary. Spectral relaxation method is applied here to solve the nondimensional conservation equations. The results show the illustration of the impact of skin friction coe cient, different physical parameters, and the heat transfer rate. The nano uid motion is enhanced with increase in the value of the internal heat sink or source. On the other hand, the rate of heat transfer on the stretching sheet and the skin friction coe cient are reduced by an increase in internal heat generation. This study further shows that the velocity slip increases with decrease in the rate of heat transfer. The outcome results are benchmarked with previously published results.

“…On the other hand, the most promising implication of nanofluids is the enhancement of heat transfer in modern engineering systems [21][22][23][24]. Nanofluids are prepared for increasing thermophysical properties, for instance, thermal conductivity, thermal diffusivity, thickness, and convective heat transfer coefficients that have been diverged from those of the base fluids like water, ethylene or tri-ethylene-glucose and diverse coolants, biofluids, and polymer game plans, as clarified by Choi [25] and Wong and Leon [26].…”

Abstract:A study has been carried out to examine the occurrence of multiple solutions for Copper-Water nanofluids flows in a porous channel with slowly expanding and contracting walls. The governing equations are first transformed to similarity equations by using similarity transformation. The resulting equations are then solved numerically by using the shooting method. The effects of wall expansion ratio and solid volume fraction on velocity and temperature profile have been studied. Numerical results are presented graphically for the variations of different physical parameters. The study reveals that triple solutions exist only for the case of suction.

“…Magnetohydrodynamics (MHD) has potential in many engineering branches, predominantly in the field of microfluidics, such as MHD micropumps [1,2], biological transportation, and drug delivery [3,4]. A precise microfluidic application of the problem is micromixing technology which is vital in biological processes, especially in rapid mixing of a biological fluid in a microchannel [5].…”

Abstract:The present study examines embedded open parallel microchannels within a micropatterned permeable surface for reducing entropy generation in MHD fluid flow in microscale systems. A local similarity solution for the transformed governing equations is obtained. The governing partial differential equations along with the boundary conditions are first cast into a dimensionless form and then the reduced ordinary differential equations are solved numerically via the Dormand-Prince pair and shooting method. The dimensionless entropy generation number is formulated by an integral of the local rate of entropy generation along the width of the surface based on an equal number of microchannels and no-slip gaps interspersed between those microchannels. Finally, the entropy generation numbers, as well as the Bejan number, are investigated. It is seen that surface-embedded microchannels can successfully reduce entropy generation in the presence of an applied magnetic field.
