摘要：

Here CVFEM is accounted for modeling natural convectived Fe3O4 - H2O nanomaterial flow in an annulus between two triangular enclosures. Flow analysis subjected to magneto-hydrodynamics has been elaborated. Heat transportation characteristics are described under radiation and heat source/sink aspects. Influences of effective variables for instance, Rayleigh number, heat (source,sink) factor, radiation factor, Hartmann number, aspect ratio, nano-particles shape factor and nanoliquid volume fraction versus heat transportation and flow fields have been scrutinized. Besides, a relationship describing average Nusselt number is introduced.
