“…Reddy et al [18] utilized the Kellor box scheme to illustrate their graphical results in the context of viscous fluid motion on a stretching surface. The influence of heat radiation on MHD flow of nanofluid at the stagnation point over a porous medium surface was investigated by Reddy et al [20]. Several other researchers have also contributed to the study of nanofluids [21][22][23].…”

This research adopts a three-dimensional, steady-state model of a magneto-hydrodynamic (MHD) nano-Carreau fluid. The model considers non-uniform source-sink effects, thermal radiation, Joule heating, and a rigid plate. The study examines the applications of thermophoretic and Brownian motion, taking into account the state of the stagnation point and mixed convection flow. Additionally, the research investigates MHD, porous medium, and chemically reacting properties near a stagnation point adjacent to a stretching sheet, considering momentum, thermal, and concentrated slips. The momentum, thermal, and concentrated transfer equations are simplified using the boundary layer (BL) approximation. Non-linear thermal radiation and non-uniform heat source-sink effects are obtained as results. By applying symmetry conversions, the system is transformed from nonlinear partial differential equations (PDEs) into ordinary differential equations (ODEs), which are then numerically solved. The velocity profile decreases significantly at high Hartmann numbers, while the temperature profile improves due to the effects of non-uniform heat sinks, Hartmann numbers, thermal radiation, and viscous dissipation. However, the temperature profile declines due to thermophoretic and Brownian motion parameters. As the Lewis number, chemical reaction, and concentration slip parameter values increase, the concentration profile decreases. Finally, the model is validated to ensure its accuracy.

The present study is intended to analyse the effect of heat and mass transfer on boundary layer stagnation point flow of a viscous fluid over a non-isothermal shrinking sheet subject to transverse magnetic field and variable surface temperature. The medium of flow is considered to be porous. Further, the effect of variable surface temperature and concentration are also taken care of in the present analysis. The governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) by suitable similarity transformations. The numerical simulation is carried out using Runge-Kutta method of fourth order with shooting technique. The physical significance of pertinent parameters of the flow phenomenon is studied with the help of graphs and tables. One striking outcome of the present analysis is that the unstable velocity profiles with inflection points are marked due to power law variation of temperature and concentration of the linearly stretchable bounding surface leaving aside the smooth fall in temperature and concentration (span wise) across the flow field. Further, it is noted that increase in magnetic field intensity, suction and thermal as well as mass buoyancy parameters enhance the skin friction concomitantly favouring the effective momentum transport.

This article investigates with the thermophoresis and Brownian motion effects on MHD electro-osmotic Jeffrey nanofluid peristaltic flow in an asymmetric microchannel. Well established large wavelength and small Reynolds number approximations are invoked. Numerical solutions have been evaluated for the stream function, nanofluid velocity, nanofluid temperature and nanoparticle phenomena. The computed results for nanofluid velocity, temperature, and concentration fields are utilized to determine the skin-friction, Nusselt number, and Sherwood number. The graphical results have been presented and discussed for various involved parameters. The novel features of nanofluids made them potentially significant in heat and mass transfer mechanism occurring in medical and industrial processes like microelectronics, pharmaceutical processes, hybrid engines, thermal management of vehicles, refrigerator, chiller, gas temperature reduction and so forth. These processes bear tendency to enhance thermal conductivity and the convective heat transfer more efficiently than base fluid. This unique aspect made nanofluids the topic of interest in recent time via different fluid flow models. The problem at hand is one such application of nanofluids in peristaltic flow through the asymmetric rotating microchannel.
