摘要

The proposed study systematically investigated Cobalt ferrite spinel (CoFe2O4) and Molybdenum disulfide (MoS2)-water hybridized nanofluid flow with melting heat transfer effect over a stretching/shrinking slippery wedge. The Yamada-Ota thermal conductivity model is a unique and interesting point of the research, which gives an improved heat transport phenomenon. Additionally, the insertions of thermal radiation along with slip boundary conditions energize the flow properties. These findings have significant implications for industrial applications, i.e., electromagnetic casting, cooling systems in various electronic devices, etc. Using suitable dimensionless variables via similarity transformation, in basic governing physical phenomena of flow profiles are renovated into dimensionless form. A spectral Chebyshev scheme coupled with an integrating collocation method is used for dealing with the obtained equations. The spectral method is used to derive the profiles of velocity and temperature via graphs. However, the Nusselt number and the skin friction profile are displayed graphically. Problem convergence is verified and presented in the comparison tables for certain limiting circumstances. The spectral model, which is more accurate, provides more options for solving a problem. This is the best option available, according to the data we have. When compared to both regular fluid and mono-nanofluid, the hybrid nanofluid’s heat transfer rate is far greater. The hybrid nanofluid also outperforms both the mono-nanofluid and the conventional fluid in terms of velocity boundary-layer control.
