Second law assessment of injected nanoparticles to blood flow with thermal radiation and magnetic field in conduit artery

Abstract

BackgroundThe 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. MethodsSuitable 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. Significant findingAn 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.
