The inflated heat transport rate of nanofluids is of great interest to researchers. Conviction of nanosuspension with an enhanced model under the consideration of inclined magnetic field is also vital for the enhancement of heat transport rate. Therefore, in this article, an inclined magnetic field has been considered during a boundary layer flow over an extending sheet, with the sheet being permeable. The sequels of heat radiation, thermophoresis, and Brownian parameters are also taken into consideration in this study. The importance of the study is the slip boundary conditions used for velocity, temperature, and concentration. A set of nonlinear partial differential equations is transformed into ordinary differential equations with a suitable choice of similarity variables. The set of first-order differential equations is quite difficult to solve analytically. Therefore, the numerical Runge-Kutta-Fehlberg method, accompanied with shooting technique, is used. The results of the physical components characterizing the flow phenomena, such as magnetic parameter, thermal radiation, thermophoresis, Brownian parameter, and slip parameters, are elaborated through graphs. The numerical results of physical quantities of attention are presented in tables. The existing outcome conforms to that of the previous published result in a particular case.

“…It is noticed from investigation that, increasing Dufour number diminishes the local heat transfer rate. Shehzad et al analyzed the impact of Brinkman and Forchheimer model on channel flow of incompressible single and multiwalled carbon nanotubes under the influence of magnetic field with temperature‐dependent and exponentially space dependent heat source. It is observed from their discussion that, increasing Eckert number enhances the Nusselt number profile.…”

Present research article investigate the heat and mass transfer characteristics of unsteady magnetohydrodynamic Casson nanofluid flow between two parallel plates under the influence of viscous dissipation and first order homogeneous chemical reaction effects. The impacts of thermophoresis and Brownian motion are accounted in the nanofluid model to disclose the salient features of heat and mass transport phenomena. The present physical problem is examined under the presence of Lorentz forces to investigate the effects of magnetic field. Further, the viscous and Joule dissipation effects are considered to describe the heat transfer process. The non-Newtonian behaviour of Casson nanofluid is distinguished from those of Newtonian fluids by considering the well-established rheological Casson fluid model. The twodimensional partial differential equations governing the unsteady squeezing flow of Casson nanofluid are coupled and highly nonlinear in nature. Thus, similarity transformations are imposed on the conservation laws to obtain the nonlinear ordinary differential equations. Runge-Kutta fourth order integration scheme with shooting method and bvp4c techniques have been used to solve the resulting nonlinear flow equations. Numerical results have been obtained and presented in the form of graphs and tables for various values of physical parameters.It is noticed from present investigation that, the concentration field is a decreasing function of thermophoresis parameter. Also, concentration profile enhances with raising Brownian motion parameter. Further, the present numerical results are compared with the analytical and semianalytical results and found to be in good agreement.Brownian motion, Casson nanofluid, Joule dissipation, magnetic field, squeezing flow, thermophoresis | INTRODUCTIONIn the present days, nanofluids are widely used in most of the industries, technologies, and scientific applications. For an instance, biological solutions, asphalts and glues, melts of polymers and paints, and so forth. Nanofluids are potentially suitable candidates for increasing the heat transfer rate in wide variety of applications. In many of the numerical investigations, nanofluids are treated as common pure fluids. Additionally, nanofluids are considerably used in the squeezing flows for enhancing the heat transfer characteristics. However, the unsteady heat and mass transfer process in squeezing flow of magnetohydrodynamic (MHD) viscous incompressible fluid flow between two parallel plates is one of the most important research area in the present days. Since, squeezing flows have plenty of engineering, scientific, and technological applications in most of the thermodynamic industries. For example, lubrication systems, moving pistons, hydrodynamical machines, hydraulic lifts, dispersion and formation, compression and injection, electric motors, cooling towers, reactor fluidization, polymer processing, processing of chemical equipment's, processing of food, crops damage due to freezing, transmission squeezed film and syringes ...

Magneto peristaltic flows of nanofluids play a key role in magnetic drug transport systems. Therefore, peristalsis of a nanofluid through a uniform porous medium under the influence of a uniform magnetic force is studied here.Ohmic heating and Hall aspects are incorporated in the analysis. Three distinct types of nanoparticles (ie, silver, alumina, and copper) have been used for theoretical analysis. A large wavelength and a small Reynolds number scheme are adopted in mathematical modeling. The dimensionless nonlinear system is solved using the well-known perturbation method, and physical analysis is done via graphs. A comparison of different nanoparticles is also presented. It is noticed that an increase in the Hall effects nullifies the variations, which are due to an increment in the Hartman number. The temperature of the nanofluid can be reduced by increasing the permeability of the porous medium. K E Y W O R D SHall effects, magnetohydrodynamics, nanofluids, porous medium | INTRODUCTIONThe analysis of nanofluids has attracted the attention of researchers from all over the world over the past decade. Nanofluids are prepared by suspending nanometer-sized metallic particles in conventional heat transfer fluids. This novel technique has been developed by Choi. 1 The idea of a nanofluid originated when conventional fluids were proving to be less helpful for usage in different mechanical processes because of their lesser thermal conductivity. To amplify the use of conventional fluids, their thermal conductivity is improved via the use of metals, as metals (like gold, silver, and copper) naturally have higher thermal conductivities. Carbides, metal oxides, metals, and carbon nanotubes are commonly used as nanoparticles. Their size varies in the range from 1 to 100 nm. The base fluids are oil, ethylene glycol, and water. Nanofluids have an ability to magnify the thermophysical aspects include thermal diffusively, viscosity, thermal conductivity, and convective heat transport coefficients. Such properties are the chief reason behind the diverse applications of nanofluids in domestic and industrial cooling, automobile and IT industry, modern drug delivery systems, nuclear reactors, microscale fluidic applications, extraction of geothermal power, cryopreservatives, and optics and nanocryosurgery. Such wide applications of nanofluids have persuaded motivated researchers from all over the globe to investigate different aspects of nanofluids. [2][3][4][5][6][7][8][9][10] Peristalsis is an involuntary series of muscle contractions and relaxation that takes place within the body of living beings to move biological fluids (eg, chyme, blood vessels, bile, urine, male, and reproductive cells) towards different processing units. Earthworms employ a similar treatment to drive their locomotion. Subject to its utility, the principle of peristalsis is being implemented by engineers in designing many industrial appliances, for example, peristaltic pumps. Such pumps are particularly useful in driving sensitive/corrosive and reactive ...
