Magnetohydrodynamic dusty nanofluid flow over a moving plate with two different boundary conditions

Currently, there are different issues related to low thermal conductivity in the conventional heat transfer fluid, such as water, ethylene glycol and oil, in engineering electronic devices. Aiming to overcome this defect in conventional fluid, this research focuses on nanofluid. Furthermore, dust...

Aiming to overcome this defect in conventional fluid, this research focuses on nanofluid. Furthermore, dust is considered because in real world, impurities exist and it may affect the flow.

The influence of non-dimensional governing parameters such as magnetic parameters and nanoparticle volume fraction on the velocity and temperature profiles for fluid and dust phases of dusty nanofluids are discussed.

The results show that CuO has the lowest velocity but highest heat transfer rate on both fluid and dust phase compared to 2 3 Al O and 2 TiO .
