ABSTRACT = {Nanofluids have enjoyed a widespread use in many technological applications due to their peculiar properties. Numerical simulations are presented about the unsteady behavior of mixed convection of Fe<sub>3</sub>O<sub>4</sub>-water, Fe<sub>3</sub>O<sub>4</sub>- kerosene, Fe<sub>3</sub>O<sub>4</sub>-ethylene glycol, and Fe<sub>3</sub>O<sub>4</sub>-engine oil nanofluids inside a lid-driven triangular cavity. In particular, a two-component non-homogeneous nanofluid model is used. The bottom wall of the enclosure is insulated, whereas the inclined wall is kept a constant (cold) temperature and various temperature laws are assumed for the vertical wall, namely: <i>θ</i> = 1(Case 1), <i>θ</i> = Y(1 – Y)(Case 2), and <i>θ</i> = sin(2πY)(Case 3). A tilted magnetic field of uniform strength is also present in the fluid domain. From a numerical point of view, the problem is addressed using the Galerkin weighted residual finite element method. The role played by different parameters is assessed, discussed critically and interpreted from a physical standpoint. We find that a higher aspect ratio can produce an increase in the average Nusselt number. Moreover, the Fe<sub>3</sub>O<sub>4</sub>-EO and Fe<sub>3</sub>O<sub>4</sub>-H<sub>2</sub>O nanofluids provide the highest and smallest rate of heat transfer, respectively, for all the considered (three variants of) thermal boundary conditions.},
