Bioconvective Darcy-Frochherimer flow of the Ree-Eyring nanofluid through a stretching sheet with velocity and thermal slips

In the current study, the bioconvective flow of Ree-Eyring through an expanding sheet with the porous medium is analyzed by considering the inclined magnetic field and gyrotactic microorganisms. Buongiorno's model, which defines the two major mechanisms; thermophoresis and Brownian motion is used to frame the mathematical model. The presence of motile cells helps in stabilizing the nanoparticle and avoids the sedimentation due to nanoparticles. The mathematical model with these assumptions is framed using partial differential equations (PDE) that are later remodeled to ordinary nonlinear differential equations by incorporating desirable similarity transformation. The equations so obtained shall be solved using DTM and the outcomes are described through graphs and tables. The graphs indicated that the velocity of the nanofluid flow reduces with the increase in the porosity and similarly, the higher values of Peclet number (Pe) are found to diminish the motile density. Whereas the increase in the thermophoresis parameter enhances the thermal and mass profiles of the nanofluid.

Automated summary

In this study, the bioconvective flow of Ree-Eyring through an expanding sheet with a porous medium is analyzed. The effects of an inclined magnetic field and gyrotactic microorganisms are considered. The mathematical model, based on Buongiorno's model, is framed using partial differential equations and later solved using DTM. The results reveal the relationship between the velocity, motile density, and thermal and mass profiles of the nanofluid.
