The Tiwari-Das nanofluid model has a serious anomaly, while estimating the mass and energy transport rates. Due to the absence of clear correlations and the fact that desirable parameters fluctuate with the characteristics of nanofluids, make it unable for precise predictions. To overcome on this dispute the Tiwari-Das model is coupled with Buongiorno's theory in the current model. The Eyring-Powell fluid with suspended Zinc oxide (ZnO) and iron (F e 2 O 3) keeping different volume percentage of nanoparticles are used to create a fluid mixture. The flow originates due to stretching sheet. The flow is subjected to upright Lorentz forces, while binary chemical species are consider on the sheet surface and far field. Furthermore, the ratio, reaction diffusion and frictional dissipation are also considered. The dimensionless governing equations are reduced to first order employing shooting mechanism and solved computationally using RK-4 approach. The outcomes for frictional coefficient, energy and mass transfer rate of hybrid nanoparticles and chemical species are reviewed using various statistical charts. From the computational outcomes for drag coefficient, we can adjudged that the frictional coefficient diminished on escalating fluid primary parameter and magnetic number. Increased percentage of nanoparticles, also detract the frictional coefficient. The mechanism of slip for nanoparticles are encouraging for energy transfer. The enhancement of energy and mass is significant with diffusion ratio parameter N bt . The influence of Lewis number is diminishing function of mass transport rate. The effect of homogenous reaction is encouraging for mass transport, while the heterogeneous and Schmidt number are diminishing. [ABSTRACT FROM AUTHOR]

• Carreau iron oxide blood nanofluid flow through narrower arteries is taken into account. • This model is useful for nano-drug delivery and cancer treatment. • Irreversibility phenomena during the drug delivery have discussed. • When treating cancer by melting heating, the amount of nanoparticles added must be taken into account. • The temperature is rising function of viscous dissipation and thermal radiation. The stipulated flow over an artery is optimized by adopting an artery as convergent or divergent channel with an arbitrary cross section. The standard Carreau fluid Model is used in this work to account for viscoelasticity in the whole network. The viscoelastic contribution at borders (inlet, outlet, and core region) is implemented while keeping the mathematical model parabolic character in mind. Due to low toxicity, MgO nanoparticles dispersed in blood having potent antibacterial effects against three major food-borne illnesses. Furthermore, Hypomagnesaemia is produced by a magnesium deficit in the blood, which is an additional stimulation for different diseases such as diarrhea, nausea, and decrease in appetite. To compensate for this shortage, MgO is delivered as a nanoparticle into the blood (base fluid). The mechanics of energy and irreversibility are evaluated with the contribution of viscous dissipation, Ohmic heating, and radiant heat. Suitable renovations are used to amend the system of complex PDEs into nonlinear ODEs. The numerical solutions to these ODEs are calculated using the fourth order Runge-Kutta scheme and the shooting mechanism. An elevation of radiation parameter contributes significantly to blood velocity, temperature, and entropy. The flow dynamic and energy of the blood stream is higher when nanoparticles are injected in base fluid. Bejan detracts as Brinkman number grows but increases as radiation parameter increases. High Weissenberg numbers dictate thermodynamic behavior relating to pure elastic energy. The system entropy amplifies against Rd. With increase in M , viscous dissipation irreversibility takes precedence overheat transfer irreversibility, while Be deteriorate. [Display omitted] [ABSTRACT FROM AUTHOR]

Modern nanomaterials and their flow dynamism processes promote complex chemical reactions that are necessary for the accurate synthesis of bespoke geometries at high temperatures. Such flow processes are very intricate and involve viscous behavior along with mass and heat transfer. Such flows mechanism can be controlled by external magnetic fields. Mathematical models offer an inexpensive opening into the fundamental properties of these dynamical processes. The homogeneous-heterogeneous reactions for nanofluids flow are established by invoking the Buongiorno's nanofluid model, in which the homogeneous reactions are regulated by first order kinetics occurring in the flowing liquid and the heterogeneous reactions are given by isothermal cubic autocatalytic kinetics. To testify the feasibility of this model, the steady, laminar Jaffrey-Hamel flow problem in the converging conduit is extended to rheological model. The system steady states are evaluated under the scenario where the reactant and the catalyst's diffusion coefficients are equivalent. In order to investigate heat and mass transfer analysis, viscous dissipation affirmation, Joule heating, and homogeneous-heterogeneous reactions are incorporated. The mathematical model prevailing the dimensionless function, velocity for flow, temperature for heat, and nanoparticles volume fraction for concentration are simulated numerically by means of Runge-Kutta method. The numerical algorithm has been validated in comparison to previously published research with extremely good agreement. The acquisition and detailed discussion of distributions of flow structure, heat, concentrations, and average Nusselt, Sherwood number at a wide range of critical characteristics. The fluid velocity in the conduit center increases significantly as the Reynolds number rises. By intensifying the magnetic field, the flow reversal control is accomplished. Applications in the allied domains have enormous promise since the ratio of Brownian and thermophoretic diffusivity has a significant impact on the transport mechanisms of homogeneous-heterogeneous processes. Chemical species A ∗ and B ∗ behave in fundamentally distinct ways in the reduced concentrations. [ABSTRACT FROM AUTHOR]
