T1 BIOCONVECTIVE NON-NEWTONIAN NANOFLUID TRANSPORT OVER A VERTICAL PLATE IN A POROUS MEDIUM CONTAINING MICROORGANISMS IN A MOVING FREE STREAM JF Journal of Porous Media JO JPM YR 2015 FD 2015-05-28 VO 18 IS 4 SP 389 OP 399 K1 free convection K1 porous medium K1 non-Newtonian nanofluid K1 gyrotactic microorganisms AB A mathematical model for natural convective flow along a vertical plate in a moving free stream in a porous medium which is filled with non-Newtonian nanofluids and gyrotactic microorganisms is presented. The effect of the viscous dissipation is taken into account in the energy equation. The governing boundary layer equations are cast into dimensionless form and then converted into a system of coupled nonlinear ordinary differential equations by using similarity transformations. The transformed equations are then solved numerically by the implicit finite difference method. The effects of the controlling parameters on the dimensionless velocity, temperature, nanoparticle volume fraction, and the motile microorganism, as well as on the local Nusselt, Sherwood, and the motile microorganism numbers are investigated, the results analyzed and then presented. The nanofluid and bioconvection parameters were found to have strong effects on the local Nusselt, Sherwood, and the motile microorganism numbers. The numerical results are compared with published data, and an excellent agreement has been found. The present study finds application in microbial fuel cells.
