摘要：The purpose of this article is the total entropy generation minimization of the nanofluid magneto-hydrodynamic (MHD) flow through a channel formed by two parallel isothermal plates considering thermal radiation effect. Air is the main fluid and three types of nanoparticles such as Al 2 O 3 , Ti and Cu are examined. The velocity and temperature fields are obtained from solution of the momentum and energy equations analytically. The local and total entropy generation rates are calculated and then the total entropy generation rate is presented graphically versus governing dimensionless parameters. Electrical efficiency, radiation parameter, nanoparticles volume fraction, Hartman and Peclet numbers are considered in this work. The results show that there are conditions in which the total entropy generation rate could be optimized.
