Abstract
AbstractThe objective of the present investigation is to find the convex and concave shape effects on radiative hybrid nanofluid (MoS2–SiO2/water) flow. Moreover, the surface is assumed to be permeable in an attempt to achieve the suction/injection of hybrid nanofluid through the surface of a stretching/shrinking sheet. As a novelty, the flow is studied under the influence of space‐ and temperature‐reliant heat source/sink, viscous dissipation, Ohmic heating on stretching/shrinking surface embedded in a porous medium. First, similarity transformations are used to transcribe the momentum and thermal equations in nondimensional form, and then Runge–Kutta–Fehlberg method is used to solve the hybrid nanofluid flow problem numerically. Effects of the convex and concave shape of the sheet with nanoparticles volume fraction, Eckert number, space‐ and temperature‐dependent heat source/sink, thermal radiation parameter, and suction/injection parameter on the temperature and velocity profiles are studied. Results reveal that the convex‐shaped stretching/shrinking sheet assists both flow and thermal distribution of hybrid nanofluid (MoS2–SiO2/water) flow in comparison to the concave‐shaped sheet. The role of Eckert number and both heat source parameters is to increase the temperature of the hybrid nanofluid (MoS2–SiO2/water) flow as well as heat transfer rate at the surface of the sheet. When the volume fraction of SiO2 nanoparticles is increased from 1% to 5%, the heat transfer coefficient also increases by 15.47% and 14.28%, for flow over the convex‐ and concave‐shaped sheets, respectively.
