This investigation aims to study Hall's current effect on the peristaltic flow of a Jeffrey nanofluid with variable thermal conductivity in an inclined asymmetric channel. Joule heating and oblique magnetic field effects are taken into consideration. A system of ordinary differential equations is obtained under the approximation of low Reynolds number and long wavelength, which consists of momentum, energy, and concentration equations. The influences of penitent physical parameters on the distribution of velocity, temperature, and concentration have been discussed graphically. Streamline graphs are offered in the terminus, which elucidates the trapping bolus phenomenon. The resulting equations are solved numerically using the ND Solver technique. The thermal conductivity parameter causes the pressure gradient to increase while reducing the pressure rise. Our present model can be applied to physiological flow transportation in the veins with heat transfer.

This communication investigates the simultaneous impact of the magnetic field, heat absorption and mixed convection in electroosmotically induced peristaltic flow of copper particles in the blood. The two-phase flow model is used in the microchannel with flexible walls. The thermal features of nanofluids are studied using copper nanoparticles. The Poisson-Boltzmann equation is employed to accommodate the electrical double layer in the microchannel. With Debye-Hückel, lubrication and long wavelength approximations, the problem becomes non-dimensional. Exact solutions have been calculated for velocity, stream function, pressure rise, pressure gradient and heat transfer coefficient and temperature profile. Impact of different embedded parameters on flow properties is graphically illustrated. It is found that the electroosmotic parameter strongly effects the velocity profile and bolus formation. Also, the decreasing behavior of temperature is presented, which clarifies the nanofluid as a cooling agent. The results show an increment in peristaltic pumping with rise in mixed convection while it decreases with magnetic field. Furthermore, a comparative study of pure blood and copper blood is conducted. The obtained results may be suitable in the peristaltic pump modulation for the efficient operation of a variety of industrial, biomedical and drug delivery systems in the microfluidic device.

The current paper deals with the radiative heat transfer of the peristaltic flow of the Buongiorno model nanofluid through a two-dimensional channel with a sinusoidal wall surface. A particular form of fluid transport occurring through progressive wave of expansion or contraction generating along a distensible tube containing fluid is known as peristaltic pumping, which takes place from the lower pressure region to the higher pressure region. Peristaltic transport finds several applications, such as blood pumping in heart, lung, and pharmacological delivery systems, and industrial applications-sanitary fluid transport, corrosive fluids transport, and so on. An approximate analytical solution is employed for the solution of the system of transformed differential equations with prescribed boundary conditions. The influences of physical parameters characterizing the flow phenomena are obtained and presented via graphs. The result warrants a good correlation with earlier studies in particular case. The following are the main findings: thermophoresis is favorable to enhance the fluid temperature near the channel center and also the axial velocity increases as an increase in the thermal buoyancy parameter. However, the main findings are elaborated in Section 3.
