▎ 摘　　要

In this paper, the MHD Jeffery Hamel problem with graphene oxide nanoparticles for various Hartmann number has been investigated. The present study discuss about the velocity profile in the steady 2-dimensional flow of a MHD fluid with nanoparticles between two nonparallel walls. At first a similarity transformation is used to reduce the partial differential equations modeling the flow, to a single third-order nonlinear differential equation containing the semi angle between the plates, Reynolds number, the magnetic field strength and GO nanoparticle volume fraction as parameters ethod Galerkin Optimal Homotopy Asymptotic Method has been used in order to study the problem and finally the obtained analytical result has been compared with the numerical solution in some numerical cases.
