This study investigates the problem of unsteady fourth-grade fluid flow in a rotating frame with the effects of the magnetic field and heat transfer. The non-Newtonian fluid is assumed to flow at infinity with constant acceleration. The nonlinear partial differential equation is discretized using the implicit finite difference scheme. The asymptotic interpolation method is used to satisfy the boundary condition. The analyses show that increasing the magnetic and rotating parameters reduces the velocity and thus the speed of motion. As time increases, the velocity increases. Increasing the second-and third-grade elastic parameters increases fluid velocity, while increasing the fourth-grade parameter decreases fluid velocity. The results obtained from the hybrid method converges to the solution. © 2024 Author(s).
