Abstract

Abstract: Recently, researchers are very possessive to examine the treatment of diseases caused due to the deficiency of magnesium. The deficiency of magnesium in blood caused Hypomagnesaemia, which is further stimulus for various diseases such as vomiting, sleepiness, nausea, loss of appetite etc. In order to cover such deficiency, magnesium is injected in blood (base fluid) as a nanoparticle. Based on the above applications, the current research focuses to cover the deficiency of magnesium through Powell-Eyring (Magnesium-Blood) nanofluid flow deformed by the linearly stretchable sheet in the vicinity of stagnation point. Linear thermal stratification, viscous dissipation and Joule heating are incorporated to disclose the heat transport properties. Magnetic field is implemented to the nanofluid with an angle α . A system of dimensionless governing equations is achieved through appropriate transformations. Physical behaviors of temperature and velocity fields are elaborated through comparative graphs. Skin friction, entropy generation, rates of heat transfer and Bejan number is disclosed through graphs corresponding to pertinent parameters. The well-known convergence method (Homotopy analysis method) is utilized to achieve the solution of the model. Decrement occurs in temperature field for dominant melting and thermal stratification phenomenon. Entropy has same scenario in case of dominant melting while inverse behavior in term of thermal stratification. Bejan number is de-escalates with the escalation of Eckert number. Also, it is worth mentioning that the velocity outline accelerated and temperature profile decelerated with the enhancement of melting parameter. It shows that recovery rate of magnesium patients may be enhanced through medicine with enriched magnesium nanoparticles depending on the health of the patient.
