Influence of radiative heat on MHD Cu-Si/water dusty-nanoliquid flow above an enlarging sheet

This study shows the impact of radiative heat transfer in unsteady hydromagnetic dusty nanofluid flow in the existence of a volume portion of nano/dust particles. The base fluid is water embedded with Cu (copper) and Si (silicon) nanoparticles. The modeled physical problem is converted into nonlinear ordinary differential equations using similarity variables and resolved using the bvp5c Matlab package. The results are investigated for Copper and Silicon-water dusty nanofluids, and simultaneous solutions are exhibited for liquid and dust phases. The wall resistance coefficient and the heat transmission rate are computed. The result shows that simultaneous results occurred for fluid and dust phases; flow and energy frontier layers are uneven for these phases. We found that the heat transfer performance of the Silicon-water dust nanoliquid is better than the Copper-water dust nanoliquid.
