SATS model for radial magnetic field beyond conventional approach

Background and objective: Thermal transport process has attracted researchers and engineers in recent time. It is due to innovative applications of heat transfer in various industrials, pharmaceutical and manufacturing fields. These applications include extraction of geothermal energy, solar thermal collectors, polymer extrusion, cooling of glass sheets, fertilizer production, oil recovery, nuclear reactors etc. In view of such consideration the magnetohydrodynamic Reiner-Rivlin nanoliquid flow invoking Cattaneo-Christov flux theory is considered. Flow induced is by curved stretched surface. Solutal and thermal transportation processes are discussed through Cattaneo-Christov fluxes model. Brownian movement and thermophoresis features are addressed. Heat equation comprises magnetohydrodynamics and thermal radiation. Isothermal reaction of first order is considered. Methodology: Convergent series solutions of differential systems employing Optimal homotopy analysis method (OHAM) are constructed. Convergence regions for solutions are discussed through total and individual residual errors. Results: Graphical description of temperature, liquid motion and concentration for emerging variables are examined. Nusselt number, drag force coefficient and rate of mass transport are explored. Opposite response for drag force coefficient and velocity occurs through material variable. Larger magnetic variable lead to decay liquid motion whereas reverse impact for temperature and drag force coefficient witnessed. Similar response for Nusselt number and temperature through thermal relaxation time variable is witnessed. Higher radiation corresponds to rise the thermal transport rate. Reverse behavior for concentration and mass transport rate through solutal relaxation time variable is found. It should be pointed out here that present formulation corrects the existing modeling for MHD flows by curved stretching surfaces beyond classical concepts of heat and mass fluxes through Fourier's and Fick's expressions respectively.
