Shape effects of MoS2 nanoparticles on rotating flow of nanofluid along a stretching surface with variable thermal conductivity: A Galerkin approach

Abstract

This article examines the influence of molybdenum disulfide (MoS2) nanoparticles shapes on rotating flow of nanofluid along an elastic stretched sheet. This nanofluid flow is considered in the presence of magnetic effects, thermal radiation and variable thermal conductivity. Platelet, cylindrical and brick shapes nanoparticles are discussed. Feasible similarity variables are introduced to convert the constructed set of partial differential equations (PDEs) into the system of simplified set of nonlinear ordinary differential equations (ODEs). The obtained set of ODEs are tacked by well-known Galerkin technique. The comparison of the achieved results with the published work also pondered. The comprehensive discussion regarding the effects of physical parameters on velocities, temperature, skin friction coefficient and local Nusselt number also presented with graphs. It is observed that with an increase in the thermal radiation parameter and Prandtl number, local Nusselt number decreases while the it is increases with an increase in variable thermal conductivity parameter. Moreover, the shape effects of various kinds of MoS2 nanoparticles are studied and we observed that the rate of heat transfer is enhanced when the platelet shape of molybdenum disulfide (MoS2) nanoparticles are considered. The comparison and convergence analysis shows that it can be further extended for major finding of developed model.
