Significance of magnetic field and chemical reaction on the natural convective flow of hybrid nanofluid by a sphere with viscous dissipation: A statistical approach

Hybrid nanofluid, which is a combination of Propylene Glycol (PG) – Water (H₂O) admixture and paraffin wax and sand, may be utilized as a standby for PG and (H₂O) blend in solar thermal framework. Objective of this article is the exploration of the dissipative flow propylene-glycol and water mixture based hybrid nanofluid by a sphere with chemical reaction and heat source parameters. MATLAB in-built solver bvp4c is utilized to exhibit the impacts of various parameters on regular profiles including temperature. Correlation coefficient is utilized to elucidate the impact of pertinent parameters on engineering parameters of concern, such as, surface friction factor. Main findings of this work are magnetic field is having a negative association with friction factor and chemical reaction is consuming a significant positive relationship with Sherwood number. It is witnessed that heat source and Eckert number are useful to meliorate the fluid temperature. Furthermore, validation is performed among our results and earlier published outcomes. Good agreement is detected.
