Entropy optimized stretching flow based on non-Newtonian radiative nanoliquid under binary chemical reaction

BACKGROUND AND OBJECTIVE Developed electronic mechanisms frequently deal with defies about thermal management from developed phase of heat diminution or generation of available surface area regarding heat exclusion. Such promising defy can be subjugated either by introducing an optimal geometry for chilling equipments or intensifying heat transportation attributes. Nanoliquid in this perspective executes an extraordinary function to address all such matters. Having such usefulness of entropy in view, we formulated the hydromagnetic non-Newtonian nanoliquid in frames of mixed convection. Nanoliquid model comprises Brownian movement and thermophoretic mechanisms. In addition, the novel mass transportation approach featuring binary chemically reacting species is introduced. Energy expression formulation is developed through dissipation phenomenon. Besides, new conditions for Buongiorno model along with radiating flux are considered. METHOD We obtained highly nonlinear structure. The computations of such structure are not easy. Thus we employed bvp4c scheme to tackle the nonlinear structure. RESULTS Heat transportation rate boosts subject to higher chemical reaction parameter in comparison to thermophoretic factor and Eckert number. The considered rheological model yields viscous nanoliquid situation when material factors are assumed zero. Entropy owing to habituation of respiring air is more in comparison to its frictional factor and during hefty physical action. Entropy subject to respiring air friction under respiratory region is much higher in comparison to air habituation factor. CONCLUSION Velocity rises via higher material parameter for thickening situation while opposing trend is witnessed for thinning nature of liquid. Entropy is meaningfully higher owing to breathing air condition rather than frictional impact towards tract. No doubt, entropy have a feasible association with respiratory thermoplasty which assists to handle asthma.
