Significance of Darcy porous and hydro-magnetic dynamical flow with heat transfer of Oldroyd-8 fluid with deferment of nanoparticles in wire coating process
Abstract
The wire coating method is an engineering development to cover a wire for wadding, motorized forte and ecological protection. In wire coating analysis, moreover, the polymer extruded on the wire is hauled into interior of a die occupied with melted polymer. By considering this significance, the magneto-hydrodynamic flow and heat transmission of Oldroyd-8 constant fluid with suspension of nanoparticles in the wire coating development had been investigated. The fluid with fixed viscosity is considered in porous medium. The flow is conducted with uniform magnetic field. The arising physical governing system is modelled mathematically. The mathematical model is executed by incorporation of thermal radiation and nanoparticles (Embedded in water+hematite nanoparticles). The wire coating is scrutinized mathematically with four cases ((Ω=0.5,∅=0),Ω=0.5,∅=0.05,Ω=−0.5,∅=0,Ω=−0.5,∅=0.05) with constant viscosity and also included in the Reynolds model for constant viscosity. The subsequent flow and heat transmission system were elucidated via the Runge–Kutta technique and the possessions of appropriate governing factors are presented in graphically. The outcome of the current investigation was equated with the previous available outcomes as a specific situation. The results were executed with nanofluid and without nanofluid as well as with positive and negative pressure gradients (Ω=0.5,∅=0),Ω=0.5,∅=0.05,Ω=−0.5,∅=0,Ω=−0.5,∅=0.0. It is seen that the temperature circulation is augmented due to the upsurge in magnetic parameter M. It is interesting to note that the positive pressure gradient with nanofluid has less momentum distribution compared to rest of the cases. It is also noted that the with negative pressure gradient, the distribution is more compared to positive pressure gradient case.
