Nonlinear Radiative Oblique Stagnation‐Point Flow of Jeffrey Fluid Over Stretching Cylinder

ABSTRACT A numerical study is carried out to investigate the flow and heat transfer of a viscoelastic fluid impinging obliquely over a circular stretching cylinder. Using the continuity, momentum, and energy equations, the problem is expressed as a set of partial differential equations with the proper boundary conditions. Normalized variables and similarity transformations reduced the governing equations into a system of transformed nonlinear ordinary differential equations, which is simulated numerically by employing a second‐order accurate implicit finite difference scheme. The numerical method is validated by comparing the results with previously published results. A comparative analysis of the cylinder and sheet is presented graphically to show the impact of various involved parameters on the different aspects of fluid motion and heat transfer against the similarity variable. Deborah number improves the axial velocity up to , while the time‐retardation parameter reduces the tangential velocity up to . The nonlinear radiative heat flux enhances the temperature distribution up to . Axial and tangential velocities are large in magnitude over a stretching cylinder as compared with a stretching sheet. Furthermore, nonlinear radiative heat transfer is observed over the cylinder instead of the sheet.
