Abstract: Hybrid ferrofluid flow pattern was analyzed in this article and Lorentz force has been applied to regulate the efficiency. Besides, radiation impact was added and permeability of region was considered in equations. Results show that an increase of Ha suppresses the nanomaterial flow and cooling performance of heat surface reduces It is determined that greater surface temperature of bottom wall can be obtained with impose of magnetic field. In addition, Nuave decays with reduce of permeability due to lower temperature gradient. An increase of buoyancy force characterizes a decrease of bottom wall temperature which indicates higher Nuave.
