Illustration of buoyant forces on Casson nanofluid flow through an exponentially stretching sheet with thermal radiation and chemical reaction.

The present investigation is intended to follow the characteristics of thermal as well as solutal buoyancy on the flow of non‐Newtonian–Casson nanofluid flow over the exponential stretching sheet embedding with the permeable medium. The interaction of thermal radiation along with the chemical reaction enriches the flow phenomena significantly. These properties are useful due to their recent applications in various industries as well as the biomedical area. The blood flow phenomenon described in the human body is characterized by the use of Casson nanofluid which is helpful for the drug delivery system. The suitable transformation rules are employed for the transformation of the proposed governing equation into ordinary and nonlinear. Furthermore, an approximate analytical approach such as Differential Transform Method is used for the solution of transformed governing equations. The illustration of the physical behavior of the contributing parameters involved in the flow phenomena is presented via graphs and tabular form. [ABSTRACT FROM AUTHOR]
