“…In real situations, the flow of fluids induced by stretched sheets involving heat transfer is unsteady in nature due to the sudden motion of the stretched sheet, change of temperature of the sheet and that of fluids and also due to the sudden change of concentration of nanofluids. The study becomes significant when the flow is unsteady and with variable physical parameters as presented by Hunegnaw and Kishan [21], Shukla and Rana [22], Sulochana and Kumar [23], and Venkataramanaiah [24].…”

The unsteady magnetohydrodynamics (MHD) flow of nanofluid with variable fluid properties over an inclined stretching sheet in the presence of thermal radiation and chemical reaction is studied taking into account the effect of variable fluid properties in thermal conductivity and diffusion coefficient. The governing partial differential equations are transformed into ordinary differential equations by using similarity transformation. The numerical solutions of the problem are obtained by using the fourth order Runge-Kutta method in line with the shooting technique. It is found that the increase in both thermal conductivity and radiative heat flux decreases the heat transfer rate but increases the skin friction and mass transfer rates. It is further observed that the increase in porosity parameter and magnetic field reduces the skin friction, heat, and mass transfer rates.

Heat transport keeps vital impact in field of engineering like heat spacing, air conditioning, refrigeration, and in chemical processing, such as heating of base and final products, heat recovery, tempering of containers, autoclaves, and reactors. This manuscript reveals theoretical and an experimental finding related for heat transport of unsteady cross nanofluid and chemical process with inclined magnetic field over the wedge. Heat transport is scrutinized with the existence of nonuniform heat sink source and radiation. Furthermore, mass transfer is studied with higher order chemical process, thermophoresis, and Brownian motion. Mathematical system produces nonlinear partial differential equations (PDEs) of time‐dependent velocity, energy, and concentration. Moreover, these PDEs changed into the system of nonlinear ordinary differential equations (ODEs). The obtained ODEs are passed out through shooting technique to convert the boundary value problem into initial value problem and further bvp4c took them for numerical solution. Bvp4c is MATLAB procedure, which is most convergent for numerical solution of ODEs based on RK‐45 procedure. Many applicable parameters are inspected graphically and in tabular form. Numerical outcomes related to physical quantities are hashed out in tabular form. Chemical process boosts the heat and mass transport. Higher radiation responses higher temperature and inclined magnetic strength reduces the velocity of cross nanofluid.

“…Prakash et al [9] examined the hydromagnetic two dimensional boundary layer flow of a non-Newtonian fluid accompanied by heat and mass transfer towards an exponentially stretching sheet in the presence of chemical reaction and thermal radiation using Casson model. Sulochana and Kishor Kumar [10] used shooting technique to analyze the heat and mass transfer in magnetohydrodynamic flow over a stretching sheet in the presence of thermal radiation and chemical reaction. Seth et al [11] used exact solution in closed form and numerical solution to investigate an unsteady hydrodynamic natural convection flow with heat and mass transfer of a viscous incompressible, electrically conducting, chemically reactive and optically thin radiating fluid past an exponentially accelerated moving vertical plate with arbitrary ramped temperature, embedded in a fluid saturated in a porous medium.…”

This paper investigates a chemically reactive Magnetohydrodynamics fluid flow with heat and mass transfer over a permeable surface taking into consideration the buoyancy force, injection/suction, heat source/sink and thermal radiation. The governing momentum, energy and concentration balance equations are transformed into a set of ordinary differential equations by method of similarity transformation and solved numerically by Runge- Kutta method based on Shooting technique. The influence of various pertinent parameters on the velocity, temperature, concentration fields are discussed graphically. Comparison of this work with previously published works on special cases of the problem was carried out and the results are in excellent agreement. Results also show that the thermo physical parameters in the momentum boundary layer equations increase the skin friction coefficient but decrease the momentum boundary layer. Fluid suction/injection and Prandtl number increase the rate of heat transfer. The order of chemical reaction is quite significant and there is a faster rate of mass transfer when the reaction rate and Schmidt number are increased.
