Internal energy activation stimulus on magneto-bioconvective Powell-Eyring nanofluid containing gyrotactic microorganisms under active/passive nanoparticles flux

Abstract

Influence of Stephan blowing on a three-dimensional hydro magneto-bioconvective Eyring-Powell nanofluid containing Gyrotactic microorganisms under active and passive nanoparticle flux conditions is investigated in this paper. The presence of non-linear radiation along a bidirectional stretched surface is also deliberated throughout this analysis. A comparative study is made up for active and passive nanoparticle volume control. The study is relevant to novel microbial fuel cell technologies combining the nanofluid with bioconvection phenomena. The Prandtl’s boundary layer equations, approximated by Oberbeck-Boussinesq’s are studied under suitable boundary conditions. Similarity transformation is used to transform the governing boundary layer equations to dimensionless nonlinear ordinary differential equation model. The non-linear model is then resolved by combining the Runge–Kutta method and the MATHEMATICA software. The dimensionless velocity, temperature, nanoparticle concentration and density of motile microorganisms together with the wall shear stress, Nusselt, Sherwood and density of motile microorganism number are graphically presented to visualize the effects of particular parameters. A novel idea of Stefan blowing on three-dimensional space taking into consideration the non-linear radiation is implemented in the investigation of Eyring-Powell flow over a deformable sheet under the effects of slip and activation energy for the first time. Axial Newtonian slip decreases the momentum of the nanoflow while tangential slip augments the flow. Bio-convection parameter reduces the nanoparticle concentration of the rescaled density of motile microorganisms. Skin friction factor is dominant in passive nanoparticles flux rather than active nanoparticles flux. Passive nanoparticles help in smooth delivery of drugs which is seen here for zero mass flux. Energy transfer rate is high compared to active nanoparticle volume control. A zero mass flux acts as a cooling agent in this study by diffusing more heat from the system.

Numerical Investigation of Radiative Hybrid Nanofluid Flows over a Plumb Cone/Plate

“…Finally, several researchers have investigated non-Newtonian nanofluids containing microorganisms. The effects of MHD and thermal radiation models on bio-convective non-Newtonian fluid flow over a stretching surface were studied by Dulal Pal et al [34], Anas et al [35], Sreenivasulu et al [36], and Mahdy [37]. Bio-convective fluid flow over a disc subjected to constant heat, mass, and microorganism boundary conditions was studied by Rahila Naza et al [38].…”

Numerical Calculation of Thermal Radiative Boundary Layer Nanofluid Flow across an Extending Inclined Cylinder

“…Waqas et al [19] discussed the numerical analysis of fluid moving on a rotating disk and highlighted the impact of microorganisms on the fluid containing nanoparticles for advanced cooling applications. Sreenivasulu et al [20] studied the fluid flow where the fluid contained gyrotactic microorganisms under the influence of nanoparticles' flux for some new advanced applications in modern science. Furthermore, research containing gyrotactic microorganisms is famous in various industrial and practical applications.…”
