Abstract
Hybrid nanomaterials is a material which combines chemical and physical characteristics of various liquids instantaneously and gives these characteristics in a uniform phase. Nanotechnology are prominent in various fields of engineering, biomedicine, industrial, advanced nanotechnology, pharmaceuticals and biological engineering. In view of such applications the objective of current study is to discuss entropy analysis for hydromagnetic radiative flow of ternary (TiO2+Fe2O3+SiO2/WEG) nanofluid by an exponentially stretching surface. Ternary nanofluid consists of three nanoparticles in conventional liquids. Here titanium dioxide (TiO2) ferric oxide, (Fe2O3) and silicon dioxide (SiO2) are used as nanoparticles. Mixture of water (H2O) and ethylene glycol (C2H6O2) are used as base fluid. Radiation, dissipation and Ohmic heating in thermal expression are accounted.
Nonlinear dimensionless systems are developed invoking useful transformations. Nonlinear systems are numerically solved by local similar method via Newton built in-shooting technique.
Outcomes of fluid flow, temperature and entropy rate with variation in sundry parameter are emphasized. Computational outcomes of thermal transport rate and drag force for sundry parameters are emphasized. Velocity decreases with variation in magnetic parameter while reverse effect holds for entropy and thermal fields.
Higher estimation of porosity variable declines the fluid flow, while reverse impact holds for drag force. An improvement in radiation corresponds to rise in entropy rate and temperature. Decay in thermal field is noticed for Prandtl number. Entropy generation boosts up with variation of Brinkman number A similar trend holds for heat transport rate through radiation and Eckert number. Entropy rate against diffusion parameter is augmented. Comparative studies are also presented.
