Abstract
This current study concentrates on the ascendency of entropy generation (EG) in a magneto- bioconvective slip flow of a Cross nanofluid containing gyrotactic microorganisms over an extending cylinder in attendance of Arrhenius activation energy and binary chemical reaction. Buongiorno's model is assimilated to explore haphazard motion and thermo-migration assessments. The proposed problem is converted to a system of higher-order nonlinear ODEs by exploiting the boundary-layer approximation and adequate similarity transformation. The subsequent ODEs are numerically tackled via the engaging well-known fourth-order Runge-Kutta-Fehlberg shooting technique. The results disclose that the velocity profiles are getting an accentuation due to elevation in slip factor. In addition, the Sherwood number is energised due to an increment in activation energy, while it is abated for augmenting the chemical reaction parameter. It is also markable that the entropy creation rate is boosted up for improving Lorentz force and haphazard movement, but the reverse attribute is communicated for thriving activation energy.
