A magneto-bioconvective and thermal conductivity enhancement in nanofluid flow containing gyrotactic microorganism

The current article scrutinizes the magneto-bioconvective of nanofluid flow through a rotating cone using Cattaneo-Christov heat flux model. Additionally, we analyzed about cross diffusion (thermo-diffusion, diffusion-thermo), porous medium, Stefan blowing and Navier slip effects respectively. The governing equations are converting into system of self-similar ordinary differential equations by using suitable transformation. A parametric study focusing the impact of involved parameters on different fields such as motile microorganisms density, nanoparticle concentration, temperature and (swirl, tangential) velocities are plotted via graphs along with the motile microorganisms density numbers, Sherwood number and local Nusselt number are analyzed through table. As a matter of fact is temperature field declined for increasing thermal relaxation parameter gamma. An increase in magnetic parameter M resembles to diminish in energy field. The suction of wall is noted for different number of when flow of swirl is reduce meanwhile injection blowing reveals conversely. The swirl velocity field diminishes to free stream from wall (cone surface) with every numbers of N-r including for stationary cone (N-r = 0). Further, Dufour (Du) and Soret (Sr) number have entirely reverse behavior on temperature and nanoparticle concentration fields.
