In this study, the problem of two-dimensional, laminar ferrofluid flow in a semi-annulus enclosure with sinusoidal hot wall is investigated numerically by using the dual reciprocity boundary element method. The flow is under the influence of a nodal magnetic source placed below the mid of the sinusoidal inner wall. The equations governing the present problem are obtained under the principles of ferrohydrodynamics and magnetohydrodynamics. The numerical computations are performed for various values of Rayleigh, Hartmann and magnetic numbers. The obtained results are depicted in terms of streamlines and isotherms which show that the effects of aforementioned physical parameters on the flow field and temperature distributions inside the enclosure.
