Abstract
This paper discusses two-dimensional heat flow of an incompressible non-Newtonian hydromagnetic fluid over a power-law stretching curved
sheet. The energy equation of the flow problem considers a radiative flux influenced by viscous dissipation and surface frictional heating. Lorentz
force and Joule heating are taken in the consequence of applied variable magnetic field satisfying solenoidal nature of magnetism. The governing
equations are reduced to boundary-layer regime using dimensionless quantities and the resulting PDEs are converted into ODEs by suitable
similarity variables. The flow fields; velocity and temperature are computed numerically by implementing Keller-Box shooting method with
Jacobi iterative technique. Error analysis is calculated to ensure solutions’ convergence. Interesting flow parameters are examined and plotted
graphically. Results show that velocity is increased for large number of fluid rheology and opposite effects are recorded for increasing curvature,
Lorentz force, and stretching power. Flow past a flat and curved surfaces are substantial in validation of this present work.
