Abstract

The current investigation interprets the flow and the thermal characteristics of the ternary nanofluid composed of MoS2, ZnO, and SiO2 spherical nanoparticles and water. The resulting nanofluid is MoS2−ZnO−SiO2−(H2O+EG) where (H2O+EG) act as the base fluid which help in the flow and the nanoparticles contribute to enhancing the heat conductivity. The flow is assumed to occur across a thin needle whose surface is maintained at a higher temperature than the surroundings. The mathematical model is framed by incorporating radiation introduced by Rosseland in terms of partial differential equations (PDE). This system of equations governs the flow and thermal properties of fluid which are converted to a system of ordinary differential equations (ODE). The major outcomes of the study indicated that the increase in the amount of molybdenum disulfide enhanced the heat conducted by the nanofluid whereas it reduced the flow speed. The positive values of the heat source/sink parameter caused the heat conduction of the nanofluid to go high.
