The textbook "Numerical Analysis of Viscoelastic Fluid from an Inclined Plate" offers a comprehensive examination of the numerical analysis of viscoelastic fluids in a specific physical context. It addresses the flow over an inclined surface, taking into account factors such as thermal radiation, radial magnetic fields, Navier-slip, Newtonian heating, and jump conditions. The authors employ the Jeffrey's Fluid model to describe the non-Newtonian behavior of the fluid under investigation. The mathematical modeling leads to nonlinear partial differential equations, which are transformed into ordinary differential equations through a non-similarity-based scaling transformation. These equations are then solved using the KELLER-BOX method. The results are presented both quantitatively and qualitatively, analyzing physical quantities such as velocity, temperature, skin friction coefficient, and Nusselt number.
