| description | Bionanofluid is a nanofluid in which bioconvection occurs. This paper studies the three
dimensional steady stagnation point flow of a bionanofluid with variable transport properties. All
the transport properties are dependent on the concentration. Zero mass flux and thermal convective
boundary conditions are taken into account. The governing equations of the problem are nondimensionalized
and transformed into a set of similarity equations using similarity transformation
generated by Lie group analysis. The transformed equations are solved numerically using the
Runge-Kutta-Fehlberg fourth-fifth order numerical method (RKF45). The solutions depend on
the viscosity parameter, thermal conductive parameter, mass diffusivity parameter, microorganism
diffusivity parameter, Schmidt number, bioconvection Schmidt number and Pe´ clet number. These
controlling parameters affect the dimensionless velocity, temperature, nanoparticle volume fraction,
microorganisms, the skin friction coefficient, the local Nusselt number and the Sherwood number as
well as the motile microorganism rate and are displayed graphically. The results were found to be in
good agreement with previous related studies. |
