Abstract
This analysis investigates the features of the mixed convection phenomenon for modified Eyring Powell fluid based on Buongiorno's relation of nanofluid. The moment of gyrotactic micro-organisms and bioconvection analysis is considered in this analysis. Energy expression incorporates the aspects of nonlinear radiation and heat sink source. Furthermore, convective heat transportation analysis and no mass flux relations are incorporated into the modeling of physical problems. The governing system represents that the rheological expression of modified Eyring Powell nanofluid is simplified and then through a transformation procedure is reduced to ODEs. The transformed ODEs are then tackled through the bvp4c technique. Important physical parameters are elaborated through graphs. Gradients of microorganisms and temperature are discussed against emerging physical parameters. Nanofluid temperature intensifies for the biot number and radiation parameter, while the quite opposite behavior of nanofluid is detected against Prandtl number. The moment of gyrotactic micro-organisms dwindles for larger bioconvection Lewis number.
