In this paper, magneto hydro dynamic (MHD) Jeffery-Hamel flow with nanoparticle has been investigated and its nonlinear ordinary differential equation has been solved through homotopy perturbation method (HPM). The governing boundary layer equations are written into a dimensionless form by similarity transformations. The effect of semi-angle has also been investigated in both convergent and divergent channel. A closed agreement between the obtained results and forth order Runge Kutta solution has been established. The proposed procedure can be applied to investigate the effect of other parameters on current problem. Key words: Magneto hydro dynamic flow, Jeffery Hamel problem, homotopy perturbation method, analytical solution.
