Description
Summary:A Sisko fluid model with non-uniform sink–source for curved surface is considered here. However, for Lorentz’s forces effects, the Hall aspects are considered. The chemical processes, radiation and thermophoresis diffusion aspects are under consideration. Mathematical modeling of existing physical model is carried out in curvilinear coordinate system and formulated system of PDEs is simplified in ODEs. Bvp4c scheme is employed for solution development. Velocity, temperature and concentration are conducted for Sisko fluid. Role of rheological parameters on velocity, temperature, and concentration are examined. It is detected that radius of curvature and temperature dependent heat sink–source significantly affect heat-mass transport mechanisms for curved surface. Moreover, velocity Sisko magneto Nanofluid boosts for larger curvature parameter. Drag force and heat transport rate are analyzed under the influence rheological parameters. Additionally, Brownian moment parameter serves to deteriorate concentration distribution. •Radiation and thermal conductivity within a Curved surface is presented.•Modeling is based on Sisko nanofluid.•Heat generation and shape factor of nanoparticles are considered.•The well-known numerical method (bvp4c) is employed for simulations.
