    Abstract

    A numerical analysis of natural convection has been performed for a two-dimensional triangular enclosure with partially heated from below and cold inclined wall filled with nanofluid in presence of magnetic field. Governing equations are solved by finite volume method. Flow pattern, isotherms and average Nusselt number are presented for 0 < Ha<100, 10 4 < Ra<10 7,0<φ < 0.05 and six cases that are made by location of heat sources. The results show in presence of magnetic field flow field is suppressed and heat transfer decreases. Furthermore it is observed that maximum reduction of average Nusselt number in high value of Ha occurs at Ra = 10 6. It is found the nanoparticles are more effective at Ra = 10 4 where conduction is more pronounced.
