RESUMO

This study aims to investigate the effects of magnetic field and anisotropic slip on the flow of Eyring-Powell fluid and heat transfer over an infinite rotating disk. Flows driven by the rotation of a disk have many practical applications in various areas of physics and engineering. The investigation of Eyring-Powell fluid flow due to the rotational motion of an infinite disk is extended for a case where anisotropic slip appears on the surface of the disk. The slip-length boundary condition has been made direction dependent by stipulating the independent slip-length values in the streamwise and spanwise direction. The flow is governed by the second-order approximation of Eyring-Powell fluid, and the numerical solution has been obtained by using bvp4c. The effects of several physical parameters such as Eyring-Powell parameter, magnetic field, and the Prandtl number have been investigated on the velocity and temperature profiles and physical quantities. The existence of a slip-length boundary condition greatly affects both the velocity and temperature profiles. The results are presented through graphs and tables, and to check their validity, a comparison has been made.
