“…Therefore, the thermophoretic parameter is expected to alter the concentration boundary layer significantly. These results fall in line with the results obtained by Zueco et al [21]. Thus, small particles suspended in a KUNDU, DAS, AND JANA gaseous medium over a turbine blade surface can cause erosion and surface roughness when there are increases in particle size.…”

The steady two-dimensional MHD mixed convective heat and mass transfer flow of a viscous incompressible electrically conducting second grade fluid past a semi-infinite stretching sheet in the presence of thermal radiation with chemical reaction and thermophoresis is analyzed numerically. Similarity solutions for the transformed governing equations are obtained and the reduced equations are then solved numerically using symbolic software MATHEMATICA. Favorable comparison with previously published work is performed. The features of the flow, heat, and mass transfer characteristics for different values of the material parameters are analyzed and discussed.

“…Faster cooling of the wall is therefore achieved with greater thermal conductivity of the micropolar fluid. Similar findings have been documented by Zueco et al It is also evident from the figures that temperature profiles overshoot for higher values of d and

k_{c}

and larger magnitudes are achieved with weak micro‐element concentration at the wall ( n = 0.5).…”

Thermophysical and wall-slip effects arise in many areas of nuclear technology. Motivated by such applications, in this article, the collective influence of variableviscosity, thermal conductivity, velocity and thermal slip effects on a steady two-dimensional magnetohydrodynamic micropolar fluid over a stretching sheet is analyzed numerically. The governing nonlinear partial differential equations have been converted into a system of nonlinear ordinary differential equations using suitable coordinate transformations. The numerical solutions of the problem are expressed in the form of nondimensional velocity and temperature profiles and discussed from their graphical representations. The Nachtsheim-Swigert shooting iteration technique together with the sixth-order Runge-Kutta integration scheme has been applied for the numerical solution. A comparison with the existing results has been done, and an excellent agreement is found. Further validation with the Adomian decomposition method is included for the general model. Interesting features in the heat and momentum characteristics are explored. It is found that a greater thermal slip and thermal conductivity elevate thermal boundary layer thickness. Increasing Prandtl number enhances the Nusselt number at the wall but reduces wall couple stress (microrotation gradient). Temperatures are enhanced with both the magnetic field and viscosity parameter. Increasing momentum (hydrodynamic) slip is found to accelerate the flow and elevate temperatures.boundary layers, magnetic field, micropolar fluids, nuclear thermal transport, numerical solutions, thermal slip, variable thermal conductivity, velocity slip | INTRODUCTIONHeat transfer is a fundamental aspect of many nuclear engineering transport processes. It may arise in any of the three familiar modes (conduction, convection, and radiation) and indeed these modes often arise simultaneously. Interesting applications include phase change saturated nucleation (see Uesawa et al 1 ), transient electrically conducting convection flows of liquid sodium, 2 nuclear propulsion systems cooling, 3 conjugate thermal transport, 4 supercritical thermal convection in rod bundles, 5 heat emission in turbulent flows of mercury, sodium, lead-bismuth, and sodium-potassium liquid metals, 6 and hybrid electrolysis systems exploiting nuclear energy. 7 Electromagnetic flows also arise in nuclear power systems wherein magnetic fields are deployed to control high-temperature electrically conducting plasmas from damaging, for example, channel walls. Magnetohydrodynamics (MHDs) concern the interaction between electrically conducting liquids and applied magnetic fields. It has extensive applications in emergency heat removal in fast reactors, 8 molten metal pumps for rapid removal of heat from cores, 9 and feeder wall thinning mechanisms in flow-assisted corrosion of alloys in nuclear reactor channels. 10 Although often the working fluids in nuclear reactor systems are air and water, many non-Newtonian liquids are increasingly being deployed.

The present paper deals with the effect of surface heat and mass transfer on magnetohydrodynamic flow of Powell-Eyring fluid over a vertical stretching sheet. The effects of thermophoresis, Joule heating and chemical reaction are also considered. The governing non-linear partial differential equations of the model are transformed into coupled non-linear ordinary differential equations using a similarity transformation and solved numerically by Runge-Kutta method and analytically by homotopy analysis method (HAM). The convergence is carefully checked by plotting h-curves. For different dimensionless parameters, numerical and analytical calculations are carried out and an investigation of the obtained results shows that the flow field is influenced considerably by the buoyancy ratio and thermal radiation, chemical reaction and magnetic field parameters. A totally analytical and consistently applicable solution is derived which agrees with numerical results.
