Numerical Investigation of the Magnetized Reactive Viscous Couple Stress Fluid Flow Down an Inclined Riga Plate with Variable Viscosity

Accurate determination of optimum flow and heat transfer condition is one the major challenges faced in application magnetic fluid field medicine engineering, especially when applied as ferrofluids for targeted drug deliveries, treatment hyperthermia, sealants computer hard drives, lubricants car shafts. In view these important applications, a mathematical investigation behavior reactive fluids containing nanostructures presented based on couple stress constitutive models. The assumed to through inclined magnetized solid boundaries energy conversion. formulation leads nonlinear coupled equations. dimensionless equations are numerically solved using spectral Chebyshev solution weighted residual technique, correctness confirmed shooting Runge–Kutta method. effects various parameters velocity, temperature, skin friction, rates described tabular graphical form, along with suitable physical explanations. Thermal analysis computations also presented. According findings, an enhanced variable viscosity reduced drag rate at bottom wall. Furthermore, thermal stability can be achieved increasing values modified Hartman number while parameter encourages instability domain.
