“…The flow transportation phenomenon in porous media has abundant advantages in environmental science, petroleum technology, electrochemical fuel cell devices, industries and hydrology such as in catalytic reactors, redesigned recovery of oil stores and warmth pipe development, soil physics (agriculture), catalytic reactors, heat removal from nuclear fuel debris, mining and mineral processing. 20−26 In 1856, a French civil engineer, Henry Darcy, laid the framework for the movement of homogeneous liquids across porous media during his work on the flow of water through sand beds. Darcy law cannot explore accurately when higher flow rates of inertial and boundary effects occur.…”

The prime intention of this study is to analyse the significance of the variable magnetic field and magnetohydrodynamic stagnation point flow of Eyring–Powell hybrid dusty nanofluid over a Darcy–Forchheimer sheet. The hybrid nanofluid was formulated by suspending the nanoparticles of copper ( Cu) and zirconium dioxide ( ZrO2) into a base fluid mixture of ( C2 H6 O2) ethylene glycol (50%) + ( H2 O) water (50%). The mixture of two different base fluid properties has notable results compared to using a single base fluid. Because when we used the mixture of both base fluids, we obtained better heat conductivity than pure ethylene glycol and a lower freezing point than water. Glycol water has several applications in solar heating installation and antifreeze in automobiles. The suitable self-similarity transformations are employed to convert the hybrid and dusty nanofluids transport equations into ordinary differential equations and then resolved using the Runge–Kutta fourth order with the shooting method in the MATLAB solver. The calculated results are plotted graphically through velocity, temperature, entropy generation, local skin friction coefficient and rate of heat transfer. The velocity profile enhances with the higher values of the Eyring–Powell fluid parameter. Entropy generation ( N G) and Bejan number ( Be) have an opposite nature on the Brinkman number ( Br). The rate of heat transfer rises for the higher values of the radiation parameter and opposite behaviour is observed to the magnetic field parameter. It is noticed that hybrid nanofluids have a higher heat transfer process than dusty nanofluids.

This research investigates an analytical solution for the slow squeeze flow of the slightly viscoelastic fluid film between two circular disks in which the upper disk approaches the lower disk with a constant velocity, and the lower disk is kept stationary. The determination of the study is to identify the behavior of the differential type fluid on the steady squeezing flow using Langlois recursive approach. The governing equations for the axisymmetric flow are expressed in cylindrical coordinates and yield the nonlinear system of partial differential equations. The analytical solution of the resulting equations with nonhomogeneous boundary conditions is obtained by the Langlois recursive approach. Flow variables such as stream function, velocity profiles, pressure distribution, shear, normal stresses, and normal force acting on the disk are determined. These flow variables are nondimensionalized by using suitable dimensional quantities. The influence of slightly viscoelastic parameter β , radial distance r , and aspect ratio on velocity components, pressure distribution, and normal squeeze force is examined mathematically and portrayed graphically. The results illustrate that the axial and radial velocities increase at the higher values of the slightly viscoelastic parameter β , which confirms the shear thickening behavior. The obtained solutions of the flow variables satisfied the existing solutions on squeeze flow of viscous fluid upon vanishing the slightly viscoelastic parameters. This solution could elucidate the classical lubrication problems, particularly in load and thrust bearing characteristics of the human body joints, the compression molding process of materials, etc.

Entropy generation is one of the most decisive factors to determine the irreversibility characteristics of various heat transport processes. Therefore, this study explores the entropy generation caused by viscous dissipation, ohmic heating, mass transfers, and chemical reactions during Newtonian flow processes through a microchannel with ciliated walls. Mathematical framework of the present model is made up of five nonlinear partial differential equations in velocity components, pressure gradient, temperature, and concentration distributions. We scrutinize nonlinear system under the lubrication approximation theory and acquire a linear system of ordinary differential equations in a wave frame of reference. Exact analytical solutions for the velocity, pressure, temperature, and concentration distributions are constructed. Expressions for entropy production rate and Bejan number are also formulated for the present flow scenario. Effects of heat and mass transfers, Hartmann number, Hall current, chemical reaction, and the eccentricity parameter of ciliary beatings on the flow field, pumping characteristics, temperature, concentration, entropy production rate, and Bejan number are discussed in details. Outcomes of present model recommend that inclusion of Hall current overwhelms the damping effects of magnetic field and hence controls the irreversibility of thermodynamical systems. Moreover, in order to manipulate the flow and irreversibility in cilia-based micro-devices, the role of eccentricity parameter is noticeable. We hope that our theoretical results can be utilized in mixing and controlling various aspects of mass, momentum, and heat transfers in MHD-based microfluidic devices.
