Numerical analysis of micropolar hybrid nanofluid

Abstract

Hybrid nanofluid has been streamlined as a new class of nanofluid, marked by its thermal properties and potential utilities which serve the purpose to enhance the rate of heat transfer. The main aim of the current analysis is to present a comparison between the behavior of traditional nanofluid and emerging hybrid nanofluid in the presence of micropolar fluid theory, rotation and porous medium over an exponentially stretched surface. The constructed mathematical differential system is solved numerically by means of the BVP-4C technique. The comparison between behavior of pure water, $$\text{C}\text{u}/\text{w}\text{a}\text{t}\text{e}\text{r}$$ nanofluid, $$\text{C}\text{u}-\text{T}\text{i}{\text{O}}_{2}/\text{w}\text{a}\text{t}\text{e}\text{r}$$ hybrid nanofluid over velocity, microrotation and temperature distribution has been visualized graphically. For better comprehension of flow characteristics and heat transfer rate, variation in skin friction coefficients in addition to the Nusselt number of nanofluid along with hybrid nanofluid is scrutinized. We perceive from the present study that the rate of heat transfer of nanofluid is lower than that of hybrid nanofluid even in the presence of micropolar effects, rotation and porosity.
