Effect of gyrotactic microorganisms on electrically conducting carreau nanofluid flow along an exponentially stretching surface in the presence of chemical reaction.

In this article, we have discussed the effects of gyrotactic microorganisms on electrically conducting carreau nanofluid across an exponentially stretching surface over a thermal radiation in the presence of chemical reaction. The governing partial differential equations and boundary conditions are converted into a system of non-linear ordinary differential equations by the using of similarity transformations which are then solved numerically using shooting technique with the help of MATLAB program. The fluid velocity is an increasing function of the local Weissenberg number, according to this research. Magnetic field influence reduces the thickness of the momentum boundary layer. Due to increased values of thermophoresis and Brownian motion effects, there is an increasing trend in carreau fluid temperature. Brownian motion causes the concentration field to decrease, whereas thermophoresis causes it to increase. The concentration profile is enhanced by activation energy, but the Schmidt number is reduced. Present results are compared with the previously published results in some limiting cases and results are found to be in an excellent agreement. [ABSTRACT FROM AUTHOR]
