Scrutinizing stagnation-point flow close to a deforming cylinder in Reiner-Rivlin fluid due to homogeneous-heterogeneous chemical reactions

This work analyzes the steady-state boundary-layer flow of a non-Newtonian Reiner-Rivlin fluid through an extended cylindrical surface. Homogeneous and heterogeneous chemical effects, magnetic field, surface curvature, suction, and injection are taken into account in the calculations. The governing partial differential equations (PDEs) are transformed into a set of ordinary differential equations (ODEs) by applying similarity transformations and then resolved numerically. The results showed that suction accelerates the fluid flow and reduces the temperature and concentration in the boundary layer, while injection leads to the opposite result. In addition, the curvature coefficient slows the flow and enhances heat transfer. Furthermore, increasing the Reiner-Rivlin coefficient of the fluid increases internal resistance, slowing the flow and reducing the temperature. A transverse magnetic field reduces velocity, raises temperature, and thickens the concentration boundary layer. Because these equations are improved, homogenous reaction rates have resulted in a substantial reduction in the species concentration. Increasing the Eckert numbers also causes an increase in the amount of viscosity that is dissipated, which ultimately results in a boundary layer that is thicker. The trustworthiness of the numerical procedure is shown by the high agreement with the findings of the prior comparison. The results obtained in this study provide a basis for the design of energy transfer systems on curved geometries.
