Influence of magnetic field on CuO–H2O nanofluid flow considering Marangoni boundary layer

Abstract Influence of magnetic field on CuO–H 2 O nanofluid forced convective heat transfer is investigated considering Marangoni convection. Similarity solution is used to obtain the ordinary equations. Runge-Kutta integration scheme is utilized to solve this problem. Influences of Hartmann number and CuO volume fraction on flow and heat transfer characteristics are presented. Results indicate that rate of heat transfer is an augmenting function of CuO volume fraction. Influence of CuO volume fraction on normal velocity is higher than tangential velocity. Nusselt number has reverse relationship with magnetic number.
