Abstract
Magnetohydrodynamic entropy optimized flow of Reiner-Rivlin liquid by stretched cylinder is addressed. Thermal relation comprises viscous dissipation, heat generation, Ohmic heating and radiation. Chemically reactive flow of binary reaction is accounted. Entropy generation is explored. Non-linear differential systems are numerically solved by Newton built in-shooting technique. Velocity, thermal field, concentration and entropy generation have been explored. Outcomes of coefficient of skin friction, gradient of temperature and mass transport rate are organized. It is noticed that fluid flow for magnetic field and curvature parameter intensifies. Drag force through magnetic field escalates while opposite trend holds for fluid variable. Thermal field against Prandtl number is decreased while opposite behavior holds for magnetic field and radiation. Temperature gradient versus radiation is decreased. Concentration decays versus Schmidt number. Decaying behavior of concentration holds for reaction variable. Solutal transport rate against reaction variable intensifies.
