Magnetohydrodynamic bioconvective flow of Williamson nanofluid containing gyrotactic microorganisms subjected to thermal radiation and Newtonian conditions

Magnetohydrodynamic (MHD) bioconvective flow of Williamson nanomaterial in frame of gyrotactic microorganisms is addressed. Nanomaterial characterizes gyrotactic microorganism. Bioconvection is generated by buoyancy forces in the communication of nanoparticles and motile microorganisms. The use of gyrotactic microorganisms into nanofluid here is just to stabilize the nanoparticles to suspend due to a phenomenon called bioconvection. Newtonian conditions for thermal, solutal and motile microorganism are employed. The transformed nonlinear systems of momentum, energy, nanoparticles concentration and motile microorganisms density are solved numerically through the bvp4c technique. Significance of various variables on physical quantities is explained graphically. (C) 2019 Published by Elsevier Ltd.
