Free convection boundary layer flow past a horizontal flat plate embedded in porous medium filled by nanofluid containing gyrotactic microorganisms
The steady boundary layer free convection flow past a horizontal flat plate embedded in a porous medium filled by a water – based nanofluid containing gyrotactic microorganisms in investigated .the oberbeck – boussinesq approximation is assumed in the analysis. The effects of bioconvection parameters on the dimensionless velocity ,temperature, nanoparticle concentration and density of motile microorganisms as well as on the local nusselt, Sherwood and motile microorganism number are investigated and presented graphically. In the absence of bioconvection , the results are compared with the existing data in the open literature are found to be in good agreement .the bioconvection parameters strongly influence the heat,mass ,and motile microorganism transport rates
