Here the Reiner-Rivlin model is applied to explore non-Newtonian flow in stagnation-point region around a stretching cylinder. Under influence of viscous heating and thermos-diffusion, phenomena combined heat mass transport investigated. To intrinsic irreversible nature phenomena, current work incorporates an analysis entropy generation. Additionally, prescribed wall temperature concentration are taken into consideration when developing computational framework, it will be shown later that these assumptions essential achieving self-similar analysis. Numerical computations developed by MATLAB tool "bvp4c" while analytical solutions found optimal homotopy approach embedded routine "BVPh 2.0" MATHEMATICA. For reasonable choice parameters, both techniques produce same numerical results. various regulating importance curvature effects on boundary layers explained. Flow visualization utilizing streamlines isotherms reveals interesting patterns for Newtonian flows. The force required cylinder analyzed evaluating skin friction coefficient, case fluid. Furthermore, surface cooling rate flux scrutinized graphically tabular form. cylindrical higher than flat plate boundary. noticeable reduction increasing values fluid parameter.

Abstract The effects of viscous force on magnetohydrodynamic flow in coaxial cylinders are discussed this article. inner cylinder stretches linearly along the axis, while outer rotates with some fixed angular velocity. movement fluid between these concentric depends stretching and cylinder's rotation. Understanding type is crucial for applications engineering industrial processes, such as magnetic materials processing transport rotating machinery. surface also considered slippery, that is, first order slip condition incorporated internal surface. impact dissipation calculated current study. After using suitable transformations, we turn mass conservation, Navier‐stokes, energy equations into dimensionless ordinary differential equations. Meanwhile, numerical solutions conducted via shooting method. outcomes graphically presented by varying values certain parameters like curvature parameter, gap cylinders, so forth. It noted expanding size enhances velocity fluid, accompanied a rise temperature. Additionally, findings indicate smaller exhibit higher heat flux rate. novelty work lies combined dissipation, conditions, MHD transfer, offering insights beyond what has been previously explored literature.
