摘要：

In this paper, we investigate the hydromagnetic bioconvection of gyrotactic microorganisms past a permeable vertical plate embedded in a porous medium filled with a water-based nanofluid. The model for the nanofluid, proposed by Kuznetsov and Nield [23], incorporates Brownian motion, thermophoresis, bioconvection of gyrotactic microorganisms and chemical reaction. Using appropriate similarity transformations, the model boundary value problem is tackled numerically using bvp4c function from Matlab. The influences of bioconvection parameters, chemical reaction parameter, inverse Darcy number etc on the velocity, temperature, nanoparticle concentration and the micro-organisms density profiles are analyzed and discussed in detail. A comparative analysis of our results with previously reported results in the literature is given.
