Abstract
Here, we investigate magnetohydrodynamic flow of an incompressible Reiner–Philippoff fluid over a stretched surface. The stretching property of the sheet induced flow. Joule heating and dissipation effects are considered in energy communication. The energy equation is developed through the first law of thermodynamics. Irreversibility analysis is constructed. Furthermore, the first-order chemical reaction is also accounted. Adequate transformation is used to get the ordinary differential system tackled through a local non-similar technique via the built-in Matlab function bvp4c. Prominent characteristics of flow parameters on the entropy rate, temperature, velocity, and concentration are studied. Thermal and solutal transport rates are studied. Reverse impacts for velocity and temperature are noted for the Reiner–Philippoff liquid parameter. Reduction in velocity is seen for the Bingham number. A larger Prandtl number reduces temperature distribution. Concentration is decreased for both the Lewis number and chemical reaction parameter. A reverse trend is observed for the entropy rate against Brinkman and Bingham numbers. A larger magnetic variable enhances entropy generation.
