Gold-based metal nanoparticles serve a key role in diagnosing and treating important illnesses such as cancer and infectious diseases. In consideration of this, the current work develops a mathematical model for viscoelastic nanofluid flow in the peristaltic microchannel. Nanofluid is considered as blood-based fluid suspended with gold nanoparticles. In the investigated geometry, various parametric effects such as Joule heating, magnetohydrodynamics, electroosmosis, and thermal radiation have been imposed. The governing equations of the model are analytically solved by using the lubrication theory where the wavelength of the channel is considered large and viscous force is considered more dominant as compared to the inertia force relating the applications in biological transport phenomena. The graphical findings for relevant parameters of interest are given. In the current analysis, the ranges of the parameters have been considered as: [Formula: see text]The current results reveal that, A stronger magnetic field leads the enhancement in nanoparticle temperature and shear stress, and it reduces the velocity and trapping bolus. The nanoparticle temperature rises with the increasing parameters such as Brinkman number and Joule heating parameter.

Micro uidic technology and Micro Electromechanical Systems (MEMSs) have received much attention in science and engineering elds over the last few years. MEMSs are found in many areas like heat exchangers, chemical separation devices, biochemical analysis, and micro pumps. Keeping these facts in mind, the prime purpose of the current paper is to present the ow of Carreau nano uids through a microchannel with electro-osmosis, Joule heating, and chemical reactions. The e ect of the external magnetic eld is considered into account. For the problem formulation, the Cartesian coordinate system is considered. The perturbed solutions are presented by making use of regular perturbation method. The graphical results are prepared based on di erent values of uid ow phenomena like velocity, temperature, solutal nano-particle concentration, Sherwood number, and Nusselt number with di erent uid variables. According to our analysis, velocity decrement is identi ed with respect to enhancing the magnetic parameter (Hartmann number). The Schmidt number, Radiation term, Prandtl number, and chemical reaction term increased the solutal nano-particle concentration. The outcomes of the Newtonian liquid model can be obtained from our scrutiny. The present scrutiny has many applications in engineering sciences such as electromagnetic micro pumps and nanomechanics.

“…For instance, Ramesh [14] investigated and discussed the Poiseuille flow of an incompressible magnetohydrodynamic Jeffrey fluid between parallel plates through homogeneous porous medium using slip boundary conditions under the effect of heat transfer. Sridhar and Ramesh [15] dealt with the magnetohydrodynamic and electroosmotic radiative peristaltic Jeffrey nanofluid flow with the effect of slip and convective boundary conditions in the nonsymmetric vertical channel. Yang and Jian discussed the electromagnetic flow of Jeffrey fluid in a parallel microchannel [16].…”

The unsteady electroosmotic flow (EOF) for one kind of linear viscoelastic fluid, which is Jeffrey type fluid, is investigated under the common impact of vertical magnetic field, external electric field, and pressure at high Zeta potential in a circular microchannel. The numerical solutions of the potential and velocity distributions are obtained by solving the nonlinear Poisson-Boltzmann equation, the constitutive equation of the Jeffrey fluid, and the Cauchy momentum equation applying the Chebyshev spectral method and the finite difference method. By contrast, the Chebyshev spectral method has higher accuracy and less computation. The flow characteristics of Jeffrey fluid at high Zeta potential are analyzed with the numerical solution obtained by the Chebyshev spectral method. The results show that the velocity of Jeffrey fluid increases with the increase of the wall Zeta potential and electric width. The oscillation amplitude of velocity distribution increases with the increase of relaxation time but decreases with the increase of retardation time. When the Hartmann number is smaller, the increase of relaxation time leads to the increase of velocity; when the Hartmann number is larger, the increase of relaxation time leads to the decrease of velocity. No matter what the Hartmann number is, the velocity always decreases with the increase of the retardation time. The velocity tends to be stable gradually with the increase of time.
