Thermal energy investigation of magneto-hydrodynamic nano-material liquid flow over a stretching sheet: comparison of single and composite particles

Abstract

The foremost purpose of the current study is to examine the heat transmission characteristics of two-phase and hybrid phase rotating nanofluid flow in three dimension over the stretchable sheet in the applied magnetic field. The novelty of this work is that due to numerous applications it considers a new sort of nanofluid i.e. hybrid nanofluid. Water is utilized as base fluid while silver,Ag and molybdenum disulfide, MoS2 are used as nanoparticles in the current study. The nanofluid is rotating around the straight-up axis with a fixed angular speed ω∗. The resultant nonlinear partial differential equalities are transformed into ordinary differential equations via a resemblance transformation. The numerical results are obtained at Matlab by using the bvp4c technique. Rotation parameter increases while stretching ratio parameter decays the temperature transference rate. In this particular research, the temperature transmission rate of hybrid nanofluid Ag/MoS2-water was found higher than Ag-water nanofluid in the existence of the magnetic effect. The temperature transmission rates of hybrid nanofluid can be achieved higher by using a suitable combination of nanoparticles.
